A force of 470N is exerted on the pedal cylinder of an automatic hydraulic system. The pedal cylinder has a diameter of 0.425 cm. How much pressure is transmitted in the hydraulic system? Express your answer in atmospheres. atm

Water flows at 1 m/s from a hot water heater, through a 410 kPa pressure regulator. The pressure in the pipe supplying an upstairs bathtub 3 m above the heater is 350 kPa. What’s the speed in this upstairs pipe? (Numerical answer is assumed to be in m/s)

A swimming pool of width 10.0 m and length 29.0 m is filled with water to a depth of 3.5 m. Calculate pressure on the bottom of the pool due to the water.

A pipe with a radius of 51 cm has water flowing at 5.3 m/s. If water goes into a new pipe with radius 21 cm, how much will the pressure decrease? ΔΡ- unit Pa

Water flows in the system shown below. The flow exits the pipe at a speed of 4.0 m/s.(a). What is the water pressure when it exits the pipe?(b). What is the height of the column of water?

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

A dump truck uses a hydraulic cylinder, as the drawing illustrates. When activated by the operator, a pump injects hydraulic oil into the cylinder at an absolute pressure of 2.91 x 106 Pa and drives the output plunger, which has a radius of 0.180 m. Assuming the plunger remains perpendicular to the floor of the load bed, find the torque that the plunger creates about the axis identified in the drawing. 3.50 m Output plunger Axis Load bed Input for hydraulic oil

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
