A pump pumps water from a cistern into an empty water tank 10.0 m high. In 5.00minutes the pump fills the water tank, whose capacity is 1200 liters. (a) What pressuredoes the pump exert at the beginning of the pipeline? (b) What is the power developedby the bomb? (Where g = 9.8 m/s^2 and water density p = 1000 kg/m^3)

A company has several sensors in storage silos to detect the total pressure in the silos to ensure the tanks will not leak. Each tank is designed to withstand a maximum total pressure of 5.7 atmospheres [atm]. An engineer wants to use one of the silos to store liquid nitric acid, which has a density of 97 pound-mass per cubic foot [lbm/ft3]. If the tank is filled to a depth of 90 feet [ft], how much surface pressure in units of atmospheres [atm] can be applied to the top of the liquid inside the tank without exceeding the maximum total pressure of the silo?
A room has a width of 14.1 feet, a length of 15.5 feet, and a ceiling height of 12.0 ft. The average flow rate for this room's air conditioning unit is 3.07 m^3/s. How many SECONDS will it take for the air conditioner to cycle the volume of air in the room?
Suppose you measure a standing person’s blood pressure by placing the cuff on his leg 0.495 m below the heart. For this problem, assume that there is no loss of pressure due to resistance in the circulatory system (a reasonable assumption, since major arteries are large). The density of blood is 1.05 × 103 kg/m3. Calculate the systolic pressure you would observe, in units of mm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the to (and greater) number is systolic pressure. Ps? Calculate the diastolic pressure you would observe, in unites of mm Hg, if the pressure at heart was 120 overc80cmm Hg. Note that the bottom (smaller) number is the diastolic pressure.Pd?
Hoover Dam on the Colorado River is the highest dam in the United States at 221 m, with an output of 1300 MW. The dam generates electricity with water taken from a depth of 105 m and an average flow rate of 670 m3/s. (a) Calculate the power in this flow in watts. (b) What is the ratio of this power to the facility's average of 680 MW?
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)
Assume that a raindrop has a volume of 0.05 cm^3 and you need an Avogadro's number of raindrops to fill up the cubic water tank. What is the length of the edge of the tank?
The plunger of the hydraulic lift in a gasoline service station has a diameter of 1 inch. It is operated by a compressed air (density = 63 kg/m3) from the tank in which the pressure is 9.315 x 105 pascals. The output piston and the rack on which the car rests are 2 feet lower than the input plunger and together weigh 1,336.33 newtons. What is the weight of the heaviest car that can be lifted if the output piston has a diameter of 1 foot? Assume 80% efficiency of the machine.
Hoover Dam on the Colorado River is the highest dam in the United States at 221 m, with an output of 1300 MW. The dam generates electricity with water taken from a depth of 106 m and an average flow rate of 640 m/s. (a) Calculate the power in this flow in watts. (b) What is the ratio of this power to the facility's average of 680 MW?
You are with an excursion party on an exploration of the surface of Mars. You find a small lake of water of that 1.76 m. Assume the density of the freshwater is unchanged on Mars. You measure the absolute pressure at the bottom of the lake to be one 161,800 Pa. What is the absolute pressure (in atm) at the surface of the lake. Assume the value of G on Mars is 3.72 m/s^2
A company needs to pump coconut oil (den: 924 kg/m^3) from the import truck to its holding tank 17 meters above the ground. If the pump that is used is able to create 3 ATM of pressure, what will be the velocity of the oil as it enters the tank?
A cylinder is fitted with a piston, beneath which is a spring, as in the drawing. The cylinder is open to the air at the top. Friction is absent. The spring constant of the spring is 3600 N/m. The piston has a negligible mass and a radius of 0.010 m. (a) When the air beneath the piston is completely pumped out, how much does the atmospheric pressure cause the spring to compress? (b) How much work does the atmospheric pressure do in compressing the spring? * I know that a is = 0.0088422743 m but b is NOT 8.950712099 J (wrong) please show work of how to work part b.
A centrifugal pump operating under steady flow conditions delivers 2,270 kg/min of water from an initial pressure of 82,740Pa to a final pressure of 275,800 Pa. The diameter of the inlet pipe to the pump is 15.24 cm and the diameter of the discharge pipe is 10.16 cm. What is the work?
