Answer:
v=82 m/s
s=116m
Explanation:
a=20t

using condition given at t=0

c=-8
now equation becomes
v=10t²-8
v at t= 3s v=82 m/s
again


now using condition given s=50 at t=0
b=50
now equation becomes

calculating s at t=3s
s=116m
Answer: valving the pump discharge to reduce the flow will only result in an increase in the water velocity according to the laws of continuity of flow.
Q = AV = constant.
The pump speed of 150 gpm is, and will remain constant. Valving simply reduces flow area A, which is balanced out by increased velocity V of water through the pipe.
This does not affect the pump speed Q (flow rate) and hence it remains the same.
