Water pressurized to 3 ´ 105 pa is flowing at 5.0 m/s in a pipe which contracts to 1/3 of its former area. what are the pressure and speed of the water after the contraction

The pressure and speed of the water after the contraction are and 15 m/s.

Explanation:

Given that,

Pressure

Flowing speed = 5.0 m/s

Area = A

Final area

We need to calculate the pressure and speed of the water after the contraction

Using equation of continuity

Where, = area

= final area

= speed

Put the value into the formula

We need to calculate the pressure of the water after the contraction

Using Bernoulli's equation

Hence, The pressure and speed of the water after the contraction are and 15 m/s.
