Water enters a basement through a pipe 2 cm in radius at anabsolute pressure of 3 atm. A hose with a 0.5 cm radius is used towater plants 10 m above the basement. The velocity of the water asit leaves the hose is 14.45 m/s.
A) What is the flow rate?
B) Find the flow rate when the hose is 20 m above the basement.

Water flows through a water hose at a rate of Q1 = 640 cm3/s, the diameter of the hose is d1 = 2.2 cm. A nozzle is attached to the water hose. The water leaves the nozzle at a velocity of v2 = 11.6 m/s.

(a) Enter an expression for the cross-sectional area of the hose A1, in terms of its diameter, d1.

(b) Calculate the numerical value of A1, in square centimeters.

(c) Enter an expression for the speed of the water in the hose, v1, in terms of the volume flow rate Q1 and cross-sectional area A1.

(d) Calculate the speed of the water in the hose, v1, in meters per second.

(e) Enter an expression for the cross-sectional area of the nozzle A2, in terms of v1, v2, and A1.

(f) Calculate the cross-sectional area of the nozzle, A2, in square centimeters.
