Water flows through a cylindrical pipe of internal diameter 7 cm at 36m/hr . Calculate the time in minute if it would fill a cylindrical tank of radius 35 cm and height 1 m. Pls. give me te answer as soon as possible.

Speed of water = 36km/hr = 36000/3600 m/sec. = 10 m/sec.
Converting into metres, Diameter of base of tank = 2 x .35 = 0.7 m.
Volume of tank= Pi r2 h = Pi (0.35)2 * 1 m3
Let Length of pipe for cylinder be h
Pi (0.07)2 *h = Pi (0.35)2
Hence h = 25 m
Time taken to cover 25 m of pipe = 25/10 seconds. = 2.5sec.
Hope it helps....
