Question

A pipe of diameter 2.4cm discharges water at a rate of 2.8 m/s. Find the volume of water discharged in half an hour, giving your answer in litres.​

Answer 1

Answer:

20076 litres

Step-by-step explanation:

Speed=2.8 m/s

Time=1800 seconds

Length of stream of water=speed*time

=2.8*1800

=4440 m

D=2.4 cm

r=D/2=1.2 cm

Volume of cylinder=πr^2h

=3.14*(1.2)^2*4440

=2007.59 m^3

=20075.9 L = 20076 L

Hope this helped you.
