A tank 6 m long, 4 m wide and 2.5 m deep is filled through a pipe of cross-section 20 cm², with water flowing at 5 m/s. How long does the empty tank take to fill?

Question

Accepted Answer

1 h 40 min. Volume =6×4×2.5=60 m³. Flow =0.002 m² ×5 m/s =0.01 m³/s. Time =60/0.01=6000 s =100 min. (10 min treats 20 cm² as 0.02 m².)

A tank 6 m long, 4 m wide and 2.5 m deep is filled through a pipe of cross-section $20 cm^{2}$ , with water flowing at 5 m/s. How long does the empty tank take to fill?
