Question

5. A hose-pipe of cross-section area 2 cm?
delivers 1500 litres of water in 5 minutes.
What is the speed of water in m/s through the
pipe ?​

Answer 1

Answer:

Speed of water is 25m/s

Step-by-step explanation:

Given:Cross Section Area (A)

=2cm^2=>2×(10^-4) m^2=>0.0002 m^2

Rate of Flow(Q) = (1500/100)÷(5×60) m^3/sec

=> 0.005 m^3/sec

Step 1: Rate of flow= Area × Velocity

Q=A×V

0.005=0.0002×V

V=25m/s

Solution: Hence velocity of flow through pipe is 25m/s.
