Expert Answer:

Volume of water flowing per min = velocity in m/min x cross sectional area of pipe

= (10 m/min)x(πx(2.5x10-3 m)2)

Radius of cone = 40 cm/2 = 20 cm = 0.20 m

Height of cone = 24 cm = 0.24 m

Volume of the cone = πR2h/3 = π(0.20)2(0.24)/3 

Time required to fill the conical vessel = Volume of vessel/Volumetric flow rate

= (π(0.20)2(0.24)/3 )/((10)x(πx(2.5x10-3)2)

= 51.2 min
