Water is moving with a speed of 4.9 m/s through a pipe with a cross-sectional area of 4.9 cm2. The water gradually descends 9.0 m as the pipe increases to 8.8 cm2. (a) What is the speed at the lower level? (b) If the pressure at the upper level is 1.8 × 105 Pa, what is the pressure at the lower level?

A water pipe having a 2.59 cm inside diameter carries water into the basement of a house at a speed of 0.770 m/s and a pressure of 213 kPa. If the pipe tapers to 1.31 cm and rises to the second floor 6.71 m above the input point,  A) What is the speed of the water at the second floor? B) What is the water pressure at the second floor?

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

A water pipe having a 2.20 cm inside diameter carries water into the basement of a house at a speed of 0.792 m/s and a pressure of 240 kPa. If the pipe tapers to 1.44 cm and rises to the second floor 6.14 m above the input point, what are the (a) speed and (b) water pressure at the second floor? (a) Number i (b) Number i Units Units

Water is flowing smoothly through a closed-pipe system. At one point, the speed of the water is 3.0 m/s, while at another point 1.0 m higher, the speed is 4.0 m/s. If the pressure is 20 kPa at the lower point, what is the pressure at the upper point? What would the pressure at the upper point be if the water were to stop flowing and the pressure at the lower point were 18 kPa?

A horizontal pipe of cross-sectional area 0.29 m2 at height 6 m carries water at speed 1.9 m/s. The pipe turns upward and levels out again to horizontal at height 14 m, where the pipe narrows to 0.11 m. If the pressure is 202 kPa at the original height, what is the pressure in kPa at the final height? The density of water is 1000 kg/m3. kPa

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?

A water pipe having a 2.69 cm inside diameter carries water into the basement of a house at a speed of 0.883 m/s and a pressure of 230 kPa. If the pipe tapers to 1.36 cm and rises to the second floor 6.54 m above the input point, what are the (a) speed and (b) water pressure at the second floor? (a) Number i (b) Number i Units Units
