An empty tank is filled with inflow in 30 minutes. A full tank is emptied in 75 minutes with an open drain. How long does it take for an empty tank to fill up if both the inlet and outlet are open simultaneously?

Correct answer:

t =  50 min

Step-by-step explanation:

t1=30 min t2=75 min  t (1/t11/t2)=1  T=1/t11/t2=1/301/75=501=0.02 1/min  t=T1=0.021=50 min
