Water flows through a water hose at a rate of Q1 = 740 cm3/s, the diameter of the hose is d1 = 2.83 cm. A nozzle is attached to the water hose. The water leaves the nozzle at a velocity of v2 = 12.4 m/s.(a) Express the cross-sectional area of the hose, A1, in terms of d1.
(b) Calculate the numerical value of A1 in cm2.
(c) Express the speed of the water inside the hose, v1, in terms of V1 and A1.
(d) Calculate the numerical value of v1 in m/s.
(e) Express the cross-sectional area of the nozzle, A2, in terms of v1, v2 and A1.
(f) Calculate the numerical value of A2 in cm2
