Water flows at 1 m/s from a hot water heater, through a 45o kPa pressure regulator. The pressure in the pipe supplying an upstairs bathtub 5 m above the heater is 350 kPa. Whats the speed in this upstairs pipe? Answer in M/s

The spring of the pressure gauge shown in the figure below has a force constant of 1 300 N/m, and the piston has a diameter of 1.40 cm. As the gauge is lowered into water in a lake, what change in depth causes the piston to move in by 0.780 cm? m Vacuum Wwwww

The pressure drop along a length of artery is 103 Pa, the radius is 9.5 mm, and the flow is laminar. The average speed of the blood is 16.5 mm/s.Randomized Variables P = 103 Par = 9.5 mms = 16.5 mm/s a. What is the net force on the blood in this section of artery in N?  b. What is the power expended maintaining the flow in mW?

A sump pump (used to drain water from the basement of houses built below the water table) is draining a flooded basement at the rate of 0.550 L/s, with an output pressure of 3.50 x 105 N/m2. You may neglect frictional losses in both parts of this problem. (a) The water enters a hose with a 3.00 cm inside diameter and rises 3.40 m above the pump. What is its pressure (in N/m2) at this point? 383000 X N/m2 (b) The hose goes over the foundation wall, losing 2.00 m in height, and widens to 4.00 cm diameter. What is the pressure now (in N/m2)? 369000 X N/m2
