Pressure at a depth, Pascal’s principle

The conservation of mass and energy in their pressure format

A water intake at a reservoir has a radius of 0.486 m. The water flows in at a speed of 0.405 m/s. At the generator building, 183 m below the intake point, the water flows out at a speed of 9.45 m/s. 

(a) What is the radius of the outlet? 

(b) What is the difference in pressure between the intake and outlet? 

Hydraulics, buoyancy

Continuity, Bernoulli
