Calculate the volume of water and the volume flow rate in gallons per minute (gpm). (1 gallon of water weighs 8.347 pounds; 1 ft3=7.481 gal.) c2. Calculate the average velocity of water flowing through this 1.05 inch ID (inner diameter) pipe. c3. Calculate Reynolds number (the ratio of inertial to viscous forces) for this flow.
3 GPM/TON CONDENSER WATER FLOW RATE----
The flow to the WWTP is 1.5 MGD and your effluent TSS is 9 mg/l. The WAS is 7000 mg/l and you waste 11990 gallons each day. An oxidation ditch has an influent flow of .55 MGD. Jar test results show an old sludge condition settling to 350 mg/L in 30 minutes. a. Calculate the return sludge ratio. b. Calculate the desired return sludge rate in gpm.

What about design at even lower condenser water flow rates? At 1.5 gpm/ton (0.027 mL/J), I calculate that the chiller's condensing temperature would rise to 105.9(F (41.1(C) causing its isentropic ...

Q = GPM, H = Ft. Head, P = BHP, D = Impeller Diameter, RPM = Pump . Pump Law = (P2/P1) = (GPM2/GPM1)2 Solving for GPM2 = GPM1 x (P2/P1)2 P = (P GPM = Gallons Per Minute AIRSIDE FORMULA SHEET. CFM increases proportionally as RPM increase. SP increases as the square2 of the RPM. BHP increases as the cube3 of the RPM.

Q* = 20,000 gpm, H* = 225 ft, BHP * = 1250 hp. Applying the similarity laws for N2 = 900 rpm and D2 = D1 = 38 in, we obtain. Q2 = 20,000*1.478 = 29,570 gpm ans. H2 = 225*1.78 = 400.5 ft ans. BHP2 = 3290 hp ans. Thus, even small changes in the speed and size of a pump can result in significant changes in flow rate, head, and power.

where the friction loss is in feet (ft), flow rate is in gallons per minute (gpm), the pipe length is in feet (ft), and the pipe diameter is in inches (in). The friction loss can be converted to pounds per squared inch (psi), by multiplying the value in feet by 0.433.
