A horizontal pipe decreases uniformly from 150 mm diameter to 100 mm diameter in the direction of the flow of water. The pressure at the narrow section of the pipe is 2.2×105 N/m2, when the flow rate is 0.12 m3/s . Assuming there are no friction losses, calculate the pressure at the 150 mm side.

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/m²

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 fusiform aneurysm bulges or balloons out an artery on all sides (pictured below). If this aneurysm occurs in an aorta, the internal radius may increase from r₁ = 1.1 cm in the normal, healthy section to 12= = 2.2 cm in the diseased section (while staying at the same vertical height). The speed of blood m flow is v₁ = 0.42 in the normal section and the gauge pressure P₁ is 99.98 mmHg. The density of 1 S blood is 1060 kg m³ Fusiform Aneurysm Image from: http://www.okclipart.com/Fusiform-Aneurysm-Clip-Art30koqyaskv/ (a) Calculate the speed of blood v2 in the aneurysm. Answer to two significant figures. Think: What equations dictating the flow through the valve are valid, equation of continuity, Bernoulli or Poiseuille? What simplifications should you make regarding the blood flow. m V₂ = S (b) Calculate the pressure gradient AP = P aneurysm healthy aorta from the healthy aorta into the aneurysm. Think: What equations dictating the flow through the valve are valid, equation of…

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.

(c)  Water is circulating through a closed system of pipes in a two-storey house. On the ground floor, the water has a gauge pressure reading of 3.5 × 105 Pa and has a speed of 2.1 m/s. However, on the upper floor, which is 3.8 m higher, the speed of the water is 3.7 m/s. The pipe widths are different on the two floors. Calculate the pressure of the water on the upper floor of the house? Take the density of water to be 1000 kg/m

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
