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 0.750 L/s, with an output pressure of 3.00×105N/m23.00×105N/m2. (a) The water enters a hose with a 3.00-cm inside diameter and rises 2.50 m above the pump. What is its pressure at this point? (b) The hose goes over the foundation wall, losing 0.500 m in height, and widens to 4.00 cm in diameter. What is the pressure now? You may neglect frictional losses in both parts of the problem.

Water supplied to a house by a water main has a pressure of 3.00 × 105 N/m2 early on a summer day when neighborhood use is low. This pressure produces a flow of 20.0 L/min through a garden hose. Later in the day, pressure at the exit of the water main and entrance to the house drops, and a flow of only 8.00 L/min is obtained through the same hose. (a) What pressure is now being supplied to the house, assuming resistance is constant? (b) By what factor did the flow rate in the water main increase in order to cause this decrease in delivered pressure? The pressure at the entrance of the water main is 5.00 × 105 N/m2 , and the original flow rate was 200 L/min. (c) How many more users are there, assuming each would consume 20.0 L/min in the morning?

A water pipe having a 2.37 cm inside diameter carries water into the basement of a house at a speed of 0.873 m/s and a pressure of 214 kPa. If the pipe tapers to 1.24 cm and rises to the second floor 7.36 m above the input point, what are the (a) speed and water pressure at the second floor? (a) Number i (b) Number i Units Units

Water at a pressure of 4.60 atm at street level flows into an office building at a speed of 0.55 m/s through a pipe 4.80 cm in diameter. The pipes taper down to 2.50 cm in diameter by the top floor, 25.0 m above. Calculate the water pressure in such a pipe on the top floor.

A cylindrical bucket, open at the top, is 35.0cm high and 9.0cm in diameter. A circular hole with a cross-sectional area 1.75cm^2 is cut in the center of the bottom of the bucket. Water flows into the bucket from a tube above it at the mtc of 3.20x10-4 m3/s. How high will the water in the bucket rise?

A fireman climbs a 8m high ladder carrying a 5.9999in diameter hose that has a 1.4in diameter nozzle. The pump has an absolute pressure of 4atm. What is the water velocity from the nozzle? Assume that water is incompressible, its density is 1000kg/m³ , and 1 inch = 0.0254 m. The acceleration of gravity is 9.8m/s² and 1 atm = 1.01 x 10° Pa. 1. V2 = 1.50598m/s 2. V2 = 14.9645m/s 3. V2 = 21.2258m/s 4. V2 = 27.6599m/s 5. V2 = 1.15567m/s 6. V2 = 15.0089m/s 7. V2 = 1.50152m/s S 8. V2 = 27.578m/s 9. V2 = 1.15225m/s 10. "2 = 21.163m/s

Water enters a house from a ground pipe with an inside diameter of 0.02m at an absolute pressure of 4.0 x 105 Pa. A pipe that is 0.01 m in diameterleads to the second-floor bathroom 5.0m above the ground floor. The flowspeed at the ground pipe is 1.5 m/s. Find the following:(a) flow speed on the second floor; and(b) pressure.

A water pipe having a 2.92 cm inside diameter carries water into the basement of a house at a speed of 0.936 m/s and a pressure of 185 kPa. If the pipe tapers to 1.57 cm and rises to the second floor 6.94 m above the input point, what are the (a) speed and (b) water pressure at the second floor?
