1. Find kinetic energy per cubic meter of flowing blood (V =1 m') in aorta for individual at Q = 5 liter/min, radius of aorta 1 cm. The density of blood is rest. Suppose flow rate is about p-1.05-10' kg/m. R =

Two identical containers are open at the top and are connected at the bottom via a tube of negligible volume and a valve that is closed. Both containers are filled initially to the same height of 1.00 m, one with water, the other with mercury, as the drawing indicates. The valve is then opened. Water and mercury are immiscible. Determine the fluid level in the left container when equilibrium is reestablished. Number Units Water Valve Mercury 100 m 4

While taking a shower, you notice that the shower head is made up of 36 small round openings, each with a radius of 2.00 mm. You also determine that it takes 2.00 s for the shower to completely fi a 1.00-liter container you hold in the water stream. The water for the shower is pumped by a pump that is 5.60 m below the level of the shower head. The pump maintains an absolute pressure of 1.50 atm. Use g = 10 m/s?, and assume that 1 atmosphere is 1.0 x 105 Pa. (a) At what speed does the water emerge from the shower head? 1.105 m/s (b) What is the speed of the water in the pipe connected to the pump? m/s (c) What is the cross-sectional area of the pipe connected to the pump? m2

What pressure is exerted on the bottom of a 0.500-mwide by 0.900-m-long gas tank that can hold 50.0 kg of gasoline by the weight of the gasoline in it when it is full?
