Fluid Mechanics --Momentum Equation
A large weigh tank is to be used in the calibration of a flow metre. Measurements of weights as a function of time are to be made. Water enters the tank vertically from the flow metering system at a speed of 20 ft/s through a 1.5 in. diameter pipe. If the weight of the empty tank is 50 lbf, determine the scale reading at t=10 s.
I found the reading to be 74.8 lbf but the answer is 212.67 lbf.
Any help is appreciated.
