Question: The liquid-level system shown in Figure 8.1.2d has the parameter values A = 50 ft2 and R = 60 ft-1 sec-1. If the inflow rate

The liquid-level system shown in Figure 8.1.2d has the parameter values A = 50 ft2 and R = 60 ft-1 sec-1. If the inflow rate is qv(t) = 10us (t) ft3/sec, and the initial height is 2 ft, how long will it take for the height to reach 15 ft?
