80. in general - 80 ft/sec is a recommended steam velocity; Sizing Steam Pipes - in SI units x .500″ wall tube. Thanks for such detailed design . Since the Baume scale, for specific gravities of liquids lighter than water, increases inversely as the true gravity, the heaviest oil, i.e., that which has the highest true specific gravity, is expressed by the lowest figure of the Baume scale; the lightest by the highest figure. b.h.p. Dynamic suction head, as determined on test, is the reading of a gage connected to suction nozzle of pump, minus vertical distance from center of gage to center line of pump. ): (33,000 ft. pounds per minute – 746 watts – .746 kilowatts) Unit for measurement of power or rate of work, Volt-amperes: Product of volts and amperes, Kilovolt-Amperes (KVA): 1000 volt-amperes, Watt-hour: Small unit of electrical work – watts times hours, Kilowatt-hour (KWHr): Large unit of electrical work – 1000 watt-hours, Horse Power-hour (HPHr): Unit of mechanical work. Equivalent water volume flowrate Vw (m³/h), Flow velocities in pipelines — steam, liquids and gases

This weight does not account for adjustments in weight due to end finishing such as upsetting or threading. Online calculator to quickly determine Pipe Sizing by Velocity for Steam. t = Nominal (specified) Wall Thickness, inches, D = Nominal (specified) Outside Diameter, inches. Could you help me to calculate or advise me formulas.

I also woul like to know any comments regarding this program. The customary method of indicating specific gravity of petroleum oils in this country is by means of the Baume scale. Total dynamic head as determined on test where suction lift exists, is the reading of the mercury column connected to the suction nozzle of the pump, plus reading of a pressure gage connected to discharge nozzle of pump, plus vertical distance between point of attachment of mercury column and center of gage, plus excess, if any, of velocity head of discharge over velocity head of suction, as measured at points where the instruments are attached, plus head of water resting on mercury column, if any. But in step 6 as you have mentioned that  the value of Po should be equal to or more than 1.75kpa. Example: Calculate the cross sectional area of a 7″ O.D. From this area the size pipe required may be selected from the table of standard pipe dimensions. I don't have the answer to how the value of 1.75 kPa has been arrived at. D = Diameter of the pipe (mm) Q= Flow rate of steam (kg/hr) V= Velocity of Steam (m/s) Ρ = Density of Steam (kg/m3) Using the formula, The pipe size = 100 mm. I am trying to get a excel spreadsheet out of the guidelines you have provided. Suffice to say that it is from the design manual of a very well known company. Thermal expansion of steam pipes heated from room temperature to operation temperature (mm pr. With few exceptions. Atmospheric pressure at sea level is 14.7 pounds per square inch. pull x pulley radius in feet. this happens two times (see sketch). This is the theoretical distance that water manu be drawn by suction. Privacy Policy. Mile), Conversions: Volume (Liter, in³, ft³, gallon GB, gallon USA), Conversions: Power (Watt, BTU/h, HP, kJ/h), Conversions: Specific Volume (m³/kg, ft³/lb), Conversions: Specific heat (kj/kgK, BTU/lb°F), Superheated Steam — Specific volume and density, Degree of superheat — Pressure reduction by saturated steam, Cooling-water injection flowrate for desuperheater, Loss of saturated steam due to faulty steamtrap/valve or hole in pipe, back pressure 1 bar(a), Pressure-reducing station for saturated steam: Required blow-off capacity of safety valve, Condensate formed in a saturated steam heated heat exchanger, Condensate flowrate in steam pipe made from steel, Blowdown quantity and potential savings for steam boiler, Water density and specific volume 1-370°C, Equivalent water volume flowrate Vw (m³/h), Flow velocities in pipelines — steam, liquids and gases, Pipe diameter DN — steam, liquids and gases, Flow rates in pipelines — steam, liquids and gases, Main pipe size equivalent to several individual pipes, Pressure drop in steam/water pipelines and valves, Pipe values: volume, shell surface, CSA, circumference, Conversion of operating m³ into standard m³ and vice versa, Conversion of volume flowrate into mass flowrate and vice versa — liquids and gases, Conversion of mass flow into volume flow and vice versa, Calculating Kv-value for cooling-watercontrol valve GESTRAMAT CW.

Conversions: Specific heat (kj/kgK, BTU/lb°F) D = 7.000 d = 7.000 – 2(.500) = 6.000 inches, D = Outside Length, inches d = Inside Length, inches, Example: Calculate the cross sectional area of a. in inches2 x .2856 x bbls. The .875 factor is to allow for minimum permissible wall based on API criteria for OCTG and line pipe. One miner’s inch: 1 1/2 cubic feet per minute = 11.25 U.S. gallons per minute = flow per minute through 1 inch square opening in 2 inch thick plank under a head of 6 1/2 inches to center of orifice in Arizona, California, Montana, Nevada and Oregon. Calculate pressure drops in steam distribution pipe lines. Steam pipes can be sized with the table and diagram below - pressure in bar, velocity in m/s and capacity in kg/h. Conversions: Volume (Liter, in³, ft³, gallon GB, gallon USA) 2. 1. Thank you for the detail design excercise. cubic feet water x 144. Conversions: Heat (kJ, BTU) Source cannot be disclosed. I am also trying to theoretically describe the perforated tube. You can view and modify all these parameters (area, perimeter, hydraulic radius) in the advanced mode of this pipe flow calculator. Total dynamic head, as determined on tests where suction head exists, is the reading of the gage attached to the discharge nozzle of pump, minus the reading of a gage connected to the suction nozzle of pump, plus or minus vertical distance between centers of gages (depending upon whether suction gage is below or above discharge gage), plus excess, if any, of the velocity head of discharge over velocity head of suction as measured at points where instruments are attached.

I've looked at  your other work and you are usually meticulous about references and credits so that got my attention on this one. P = Minimum Internal Yield Pressure (Burst Resistance) in pounds per square inch, rounded to the nearest 10 psi. Running torque is the pull in pounds a motor exerts on a belt running over a pulley 24″ in diameter. I would appreciate suggesting excel sheet program by reader. This is because a presuure drop less than 1.75 kPa will create "flow maldistribution" in the pipe distributor which is not desirable. Internal Pressure of Minimum Yield, D 8.625 = 3043 or 3040 psig (rounded to nearest 10 psig), S = Specified Minimum Tensite Strength (60,000 psi) and, D 8.625 = 5217 or 5220 psig (rounded to nearest 10 psig), For 3. No, the method is not applicable for sonic/choked flow. Conversions: Enthalpy (kJ/kg, BTU/lb), Saturated steam table (0.1 - 221.2 bar) I have perry"s chemical engineers handbook 7'th edition. Turning effort. Conversions: Length (Meter, Inch, Foot, Yard, Mile, Naut. Horse Power (H.P. If someone wants to get it please write to my email: jvillarreal@petroterminal.com. When using a sizing program to select steam pipe sizes, the engineer or contractor is asked to fill in the capacity, the steam pressure, and the velocity required. Example: 1.02 not 1,02. However i can not find any information on choked flow through a perforated pipe. : g.p.m. what are we          calculating for?
