Question

water is flowing at 4km/h through a circular pipe of diameter 16 cm into a rectangular tank 22×20×16m how long will it take to fill the tank​

Answer 1

Answer:

87 h 32min

Step-by-step explanation:

I assume the tank is 22m x 20m x 16m (nothing else seems sensible) so its volume is 7040 cubic metres.

The XSA of the pipe is π x 0.08 x 0.08 square metres, the flowrate is 4000 m/hr

so it delivers 25.6π cubic metres per hour. (About 70 so expect answer about 100 hours to fill about 7000 cubic metres)

Therefore 87 hours 32 minutes (to nearest minute)

Answer 2

Answer:

87.5 or 87 hrs and 30 min

Step-by-step explanation:

volume of pipe=volume of tank

=>22/7 × 8/100 × 8/100 × 4000 = 22×20×16

=>2815/35 = 7040

time=7040×35/2815

=87.531... or 87 hrs 30 min (apprx)
