Answer:
24 minutes
Step-by-step explanation:
Internal diameter of the cylindrical pipe = 7c.m = 0.07m
=> radius of the pipe = 0.035m
then area of cross-section = 22/7 * 0.035 * 0.035 = 0.00385 m²
speed of water = 5m/s = > 300m/ min
therefore capacity of water from the pipe in 1 minute
= 300*.00385 m³
= 1.155 m³
ie, part of tank the pipe fills in 1 minute = 1.155 m³
capacity of the tank = 4x3x2.31 m³ = 12x2.31 m³ = 27.72 m³
therefore,
time taken to fill the tank by the pipe
= 27.72 / 1.155 minutes
= 24 minutes
