Question

5. The cross-area of a pipe is 42 cm², and water is
pouring out of it at the rate of 1.25 m per sec. If
the pipe remains full, find the number of litres
discharged per minute.​

Answer 1

Answer:

0.315 lit/min

Step-by-step explanation:

given that,

area of cross section(A) = 42cm^2

A = 42*10^-4 m^2

velocity(V) = 1.25m/s = 1.25*60 m/minute

volume flow rate(VFR) = ?

we know that,

VFR = A.V

= 42 × 10^-4 × 1.25 × 60

= 3150 × 10^-4

VFR = 0.315 litres discharges per minute
