Oil of density 780 kg/m3 is flowing at a velocity of 20 m/s at the atmospheric pressure in a horizontal cylindrical tube elevated at 25 m above the sea level. Please find the tube radius if the rate of total mechanical energy (kinetic plus potential plus flow work) for oil is 57.5 kW (i. e. 57.5 kJ/s).

radius = 0.045 m

Explanation:

Given data:

density of oil = 780 kg/m^3

velocity = 20 m/s

height = 25 m

Total energy is = 57.5 kW

we have now

E = kinetic energy+ potential energy +  flow work

solving for flow rate

solving for d

d = 0.090 m

so radius = 0.045 m
