The pressure of water pipe when tap is open and closed are 3  105 N m-2and 3·5  105 N m-2 respectively. Withopen tap, the velocity of water flowing is,

The reading of pressure metre attached with a closed pipe is 4.5×104 N/m24.5×104 N/m2. On opening the valve, water starts flowing and the reading of pressure metre falls to 2.0×104 N/m22.0×104 N/m2. The velocity of water is found to be V−−√m/sVm/s. The value of VV is _____

Water is entering at pressure 4 × 104 pascal with a velocity of 2m/s in a horizontal pipe with cross-sectional area decreasing from 2 × 10–2 m2 to 0.01 m2 . The pressure at smaller cross-section of pipe  in pascal will be :-323.43.4 × 1043.4 × 105

Water of density 1000 kg/m3 flows through a tube as shown in figure1a below.At section 1 the pressure is 200 kN/m2, the velocity is 5 m/s and the pipe diameter is0.12m. The pipe diameter at section 2 is 0.065m.Calculate: i) the velocity and pressure at section 2

Water circulates throughout a house in a hot-water heating system. Ifthe water is pumped at a speed of 0.50 m/s through a 4.0-cm-diameterpipe in the basement under a pressure of 3.0 atm, what will be thepressure in a 2.6-cm-diameter pipe on the second floor 5.0 m above ifthe flow speed is 1.2 m/s? Assume the pipes do not divide intobranches.

Water moves through a constricted pipe in steady, ideal flow. At the lower point shown in the figure below, the pressure is 1.80 ✕ 105 Pa and the pipe radius is 2.50 cm. At the higher point located at y = 2.50 m, the pressure is 1.22 ✕ 105 Pa and the pipe radius is 1.30 cm.A pipe is open at both its left and right ends. The pipe starts at the left end, extends horizontally to the right, curves up and to the right, and extends horizontally to the right again. The right end is higher than its left end, and the change in height is labeled y. The diameter at the right end is smaller than the diameter at the left end. The pressure at the left end is labeled P1, and the pressure at the right end is labeled P2.(a) Find the speed of flow in the lower section.
