Question

consider a 3 meter long pipe which tapers uniformly from 20 cm to 40cm diameter at its upper end. the pipe centre line is at 30 degree with the horizontal the flow direction of liquid is from smaller end to bigger end if the pressure at the lower end 250 kpa and pressure at upper 300 kpa. determine the rate flow

Answer 1

Assuming Steady state, in-viscid fluid flow though pipe.

Applying Bernoulli's equation at inlet at section1 and section 2.
