Question

Consider an incompressible fluid flowing from a 15cm diameter pipe into

a 5cm diameter pipe. If the velocity and pressure before the constriction

are 1m/s and 10 000 N/m2

, calculate the velocity and pressure in the

constricted pipe. Neglect the effects of viscosity and turbulent flow. To

work out the new pressure, remember that the increase in speed

involves an increase of kinetic energy, and this energy must come from

somewhere – so there will be a drop in pressure.​

Answer 1

Explanation:

1. VA= constant 15*1=5*V. V=3m/s
