- 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 0.700 L/s, with an output pressure of 2.00 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 3.00 m above the pump. What is its pressure (in N/m²) at this point? N/m² (b) The hose goes over the foundation wall, losing 1.70 m in height, and widens to 4.00 cm diameter. What is the pressure now (in N/m²)? N/m²Water 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)What flows at 0.850 m/s from a hot water heater, through a pressure regulatory at 450 kPa on the ground floor of the house. This same pipe is used to supply water to a bathtub 3.7 m higher in the household at a pressure of 414 kPa. What is the flow speed in the pipe on the same floor as the bathtub?
- 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 0.75 L/s, with an output pressure of 1.5×10^5 Pa. (a) The water enters a hose with a 2.8 cm inside diameter and rises 2.2 m above the pump. What is its pressure at this point? (b) The hose goes over the foundation wall, losing 0.55 m in height, and widens to 6.6 cm in diameter. What is the pressure now? You may neglect frictional losses in both parts of the problem.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 UnitsA typical blood pressure is 120 mm Hg. How high above the injection site would you need to hang an IV bag so that the fluid enters the blood stream at this pressure? Assume the IV fluid has a density of 1000 kg/m3. Remember, 1 mm Hg = 133 Pa
- 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 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?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
