The parallel galvanized-iron pipe system delivers water with a total flow rate of 0.036 m3/s. If the pump is wide open and not running, with a loss coefficient K = 1.5, determine the flow rate in each pipe. Use f1 = 0.0264 and f2 = 0.0282.   Choices:

A pipe connected in series has the following roughness or friction coefficients: Pipe 1 C = 80 (Hazen-Williams) Pipe 2 n = 0.015 (Chezy-Manning) Pipe 3 f = 0.025 (Darcy-Weisbach) All pipes have a diameter of 400mm, length of 1 kilometer, and flow rate of 150 L/s. Determine the headloss on Pipe 1 in meters.

Q4: The pump shown in figure (2) adds 25 kW to the water and causes a flow rate of 0.04 m³/s. Determine the flow rate expected if the pump is removed from the system. Assume f= 0.016 for both case and neglect minor losses. 40-mm-diameter nozzle (2) 60-mm-diameter, 30-m-long pipe; f = 0.016 Pump T h (1) Fig. (2)
