A pump is located 4.5 m to one side of, and 3.5 m above a reservoir. the pump is designed for a flow rate of 6 L/s. for satisfactory operation, the static pressure at the pump inlet must not be lower than -6m of water gage. determine the diameter of the standard commercial steel pipe that will give the required performance. include the minor losses. an initial guess for the pipe size of 5 cm can be used. note that: 1 m^3 = 1000 L, kinematic viscosity of water : v = 1.51*10^-6 m^2/s note: take the value of loss coefficient for regular 90 degree, threaded elbow which is k_L= 1.5.
