Ph 111 NAME __________________________________ December 8, 2008 Quiz 5 Class Average: 6.1/10 Please give your numerical answers to at least three significant figures. Please give the correct units (m/s, kg, rad/s, hour, day, etc.) with each answer. Problem 1.An underwater vehicle is exploring a region of the Pacific Ocean. The vehicle has a circular observation window with area A= 0.04 m2. If the force on the window is equal to 750,000 N, what is the depth hof the ocean at that point? [The density of ocean water is 1040 kg/m3.] The relations for pressure give FPgAhρ==Solving for the depth h,we get ()()()()23750,000 N1840 m0.04 m1040 kg/m9.8 N/kgFhAgρ===h= 1840 m Problem 2.A water pipe having a 3.0 cm inside diameter carries water into the basement of a house at a speed of 1.5 m/s. The pipe then tapers to an inside diameter of 1.5 cm.
