# steam pipe size calculation formula

Example: Power costs .01 per k.w.-hour; pump efficiency is 75%; motor efficiency is 85%; total head is 50 feet. One horse-power: 33,000 ft. pounds per minute, Cubic feet per second: Gallons per minute 449.

x .500″ wall tube. As per your literature I have workout the Required no of holes for the Perforated pipe in reactor for addition of KOH in Reactor by gravity flow . Dynamic suction lift is the vertical distance from the source of supply when pumping at required capacity, to centerline of pump, plus velocity head, entrance and friction loss, but not including internal pump losses, where static suction head exists but where the losses exceed the static suction head the dynamic suction lift is the sum of the velocity head, entrance, friction, minus the static suction head, but not including internal pump losses.

what are we          calculating for?

x head in feet, COMPUTING H.P. The formulas described below are based on full sections, exclusive of corner radii. (D) specified to ASTM A53 grade B (SMYS – 35,000 psi). Suction lift exists when the suction measured at the pump nozzle and corrected to the centerline of the pump is below atmospheric pressure. Running torque is the pull in pounds a motor exerts on a belt running over a pulley 24″ in diameter.

Gr. 9 U.S. gallons per minute in Idaho, Kansas, Nebraska, New Mexico, North Dakota, South Dakota and Utah. Online calculator to quickly determine Pipe Sizing by Velocity for Steam. The formulas described below are based on full sections, exclusive of corner radii. The cross sectional area expressed in square inches is used in various tubular goods equations. The customary method of indicating specific gravity of petroleum oils in this country is by means of the Baume scale. This is the theoretical distance that water manu be drawn by suction. at motor. Kv-Values for Steam, Liquids and Gases Example: Calculate the cross sectional area of a 7″ O.D. To illustrate, assume a piping system has been designed with the following criteria: 2. WATER DISCHARGE MEASUREMENTS: To calculate the volume being displaced through a pipe or the amount of volume of an irrigation well, the following formula is applicable: Example: Calculate the discharge of a 10″ pipe which has an area of 78.50 in2, a horizontal measurement of 12″ and a vertical measurement of 12″. Information required to calculate the required pipe size: Example 10.2.4. Amount of flash steam, DN behind trap Why don't you make an attempt to check out the results? Pipe values: volume, shell surface, CSA, circumference, Kv-Values for Steam, Liquids and Gases Box 1840

): (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. Example: 1.02 not 1,02. Conversions: Pressure (bar, psi, Pa)

because the perforated pipe is installed within a pipe there is a change in gas direction. If you continue without changing your cookie settings, we assume that you consent to our use of cookies on this device. Velocity head should be considered in accurate testing also, as it is part of the total dynamic head and consequently affects the duty accomplished. From this area the size pipe required may be selected from the table of standard pipe dimensions. Atmospheric pressure at sea level is 14.7 pounds per square inch.

A motor that has a heavy starting torque is one that starts up easily with a heavy load. 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.

If the pipe is circular, you will find it according to the following equation: R = A / P = πr² / 2πr = r / 2 = d / 4. where r is the pipe radius, and d is the pipe diameter. Nitrogen gas passes through pipe and at outlet of pipe has relief valve where conditions are changed to flowrate is 50,000 kg/hr, pressure 2 Barg and Temp. in inches, The theoretical horse-power necessary to do the work, 935 Pendell Blvd. Viscosity is the internal friction of a liquid tending to reduce flow. This table below can be used for fast calculation of steam pipes sch.

Suffice to say that it is from the design manual of a very well known company.

It can be measured directly by fastening a piece of belt to 24″ diameter pulley, wrapping it part way round and measuring the pounds pull the motor can exert, with a spring balance.

The formulas described below are based on full sections, exclusive of corner radii. The mercury column or vacuum gage will show the velocity head combined with entrance head, friction head, and static suction lift.

However, please correct me if i am wrong.

INTERNAL YIELD PRESSURE BURST-RESISTANCE (P): The internal yield pressure or burst resistance of pressure bearing pipe is expressed in pounds/square inch (psi).
