Pr 3 (25 pt): The 17 in impeller diameter pump given below, operating at 1770rpm is used to pump 3500gpm of water at 68∘F in the system shown below. The total length of pipe is 1500ft and the pipe diameter is 10in. The surface of the left tank is z1=100ft There are two 90deg regular elbows (K=1.5), and entrance (K=0.8) and exit (K=1.0) losses. The absolute roughness for cast iron is 0.00085ft. The density of the water is 62.3lbm/ft3, and the dynamic viscosity is μ=6.556×10−4lbm/ft−s. (a) (5 pt) Compute the total friction losses. (b) (5 pt) What is the head delivered by the pump? (c) (5pt ) Determine the value of z2. (d) (5pt) Compute the power delivered to the water by the pump. (e) (5pt ) Compute the power supplied by the motor.
