Water is being filled into a water tank at 22 liters/second. The base of the tank has dimensions w = 1 meter and L = 2 meter . What is the rate of change of the height of water in the tank? (express your answer in cm/sec).

Answer 1

assuming parallel sides, when

v = 2x
dv/dt = 2 dx/dt

22 liters/sec = 22/1000 m^3/s

.022 = 2 dx/dt
dx/dt = 0.011 m/s = 1.1 cm/s

Answer 2

owh, i see.. thank you Steve
