A vertical water jet flows out of a round hole. One of the horizontal sections of the jet has a diameter d = 20mm while the other section located 1 = 20cm lower has the diameter which is n = 1.5 times less. The volume of the water flowing from the hole each second is found to be 9 xx 10^(-n) cm^3/s. What is the value of n ? (Surface tension T = 0.073 N/m, and density of water = 10^3 kg/m^3).

1.	A vertical water jet flows out of a round hole. One of the horizontal sections of the jet has a diameter d = 20mm while the other section located 1 = 20cm lower has the diameter which is n = 1.5 times less. The volume of the water flowing from the hole each second is found to be 9 xx 10^(-n) cm^3/s. What is the value of n ? (Surface tension T = 0.073 N/m, and density of water = 10^3 kg/m^3).
