A hose for firefighters has an inner diameter of 8.0 cm. The pressure inside the hose is 380 kPa higher than the air pressure. The nozzle at the end of the hose has an inner diameter of 3.50 cm.

a) What is the velocity with which the water leaves the nozzle?

b) How many liter water per second leaves the hose?

Use 1.00·10^3 kg/m3 as density for water
