WebFeb 2, 2024 · First use the Hazen-Williams equation to find the velocity of the fluid: v = k × C × R 0.63 × S 0.54.In this equation, k is either 0.489 for metric or 1.318 if using imperial units, C is the roughness coefficient of … WebFor example, a 3 inch per hour rainfall will build up to a 3 inch depth on a flat roof in one hour, at the rate of 1.87 gallons per hour/sq. ft. or .0312 gallons per minute/sq. ft. (See Figure 7). Using a 10,000 sq. ft. roof area, the 3 inch rainfall will produce 18,700 gallons in one hour at the rate of 312 gallons per minute. See the following.

WebArea = 0.349 ft 2. The area of the pipe is 0.349 ft 2. Using this information, we can determine the flow rate (Q) as follows: Q = Area * Velocity. Q = (0.349 ft 2) * (16 ft/s) Q = 5.584 ft 3 … This friction loss calculator uses the Hazen-Williams equation to estimate the … WebTo do this, all we would need is a single set of experimental data for the orifice plate relating flow in GPM, pressure in kPa, and density in kg/m 3. Applying this to our original data where a water flow rate of 180 GPM resulted in a pressure drop of 45 inches water column, we could convert the pressure drop of 45 ”W.C. into 11.21 kPa and ... how are lenses used
Convert Pressure, Inch of water
WebCv Value Calculator for Fluids The Cv value for fluids can be found using the following formula: Where: Cv = Valve flow coefficient Q = Volumetric flow rate (SCFH – Standard Cubic Feet/Hour) P1 = Inlet Pressure (psia) P2 = Outlet Pressure (psia) T = Temperature (F) G = Specific Gravity of the gas Calculate the minimum Cv value of your valve below. WebExample: An area of 1000 square feet is receiving a total of 10 gallons per minute. Therefore, using the precipitation rate formula, we can determine the precipitation rate as follows: Pr = 96.25 x Total GPM. Total Area. = 96.25 x 10. 1000. Web1 gallon per minute to cubic inch/hour = 13859.99986 cubic inch/hour 2 gallon per minute to cubic inch/hour = 27719.99972 cubic inch/hour 3 gallon per minute to cubic inch/hour = … how are lentils cooked
