Question

1. A large reservoir is used as a water supply for a community. A portion of the water
supply system is shown schematically below. The water flows from the reservoir to a
large storage tank before going from there to the water treatment plant. The pipeline
from C to D consists of a rounded - edge entrance (K = 0.04), 914m of cast iron pipe
with a diameter of 610mm, three gate valves (K = 0.19), four 45° elbows (K=0.42) and
two 90° elbows (K=1.0). Between F and G there are 914m of cast iron pipe with a
diameter of 610mm, two gate valves (K=0.19), and four 90° elbows (K=1.0). The friction
factor for the pipeline is 0.017. The system is designed to provide a flow rate of 1890
lit/s with water at a temperature of 26.7°C. Determine the minimum and maximum
gage pressure in the pipeline.

QUESTION 5 Q2. Two water pipelines converge into one line of 2.5m diameter. a). What is the velocity of water flowing in the converged line if the discharges and diameters of the converging lines are 1 m3/s with an 800mm pipe and 0.5 m³/s with a 500mm pipe? (m/s) b). What is the mass flowrate under these conditions? (kg/s) c). What percentage change in velocity would there be in the converged pipe if the diameter of the pipe was reduced by 20%? Take the density of water to be 103 kg/m3. Part a). is denoted Q5, part b). as Q6 and part c). as Q7
A piping system is designed for a group of people that need to pump water with a continuous flow rate of 10 L/s from a large well in their farmland. The water level in the well is 10 meters below ground, and water must be pumped using 0.06 m internal diameter plastic pipes (roughness = 0) to a large tank at top of a hill, which is 58 meters above the well's ground level (Z1=0). The required length of piping is 500 meters. Both the tank and the well are very large reservoirs that are opened to the atmosphere (atm gauge pressure). The system contains a sharp inlet (K=0.5), an open globe valve (K=?), two 12-inches radius bend (K=0.33), a 90-degree standard elbow (K= ?), and a half open gate valve (K= ?). A.)Calculate total minor loss K coefficients B.)the amount of total head loss C.)the required head pump D.)and the motor (shaft) power (kW) using the assumption that the pump's efliciency is 70%.
