7.24 A pump is used to pressurize air in a tank to 300 kPa abs. e tank has a diameter of 2 m and a height of 4 m. The initial level of water in the tank is 1 m, and the initial pressure at the tank water surface is 0 kPa gage. The atmospheric pressure is 100 kPa. The pump provides a constant head of 50 m. The water is drawn from a reservoir that is 4 m below...

Consider a water pipe with a restricted section as illustrated
beside. The consumption meter from the utility company indicates a
constant water flow of 480 L/min. You also know that the pipe has a
diameter of 40 cm at the inlet and outlet but only a diameter of 20
cm in the restricted region.

The transfer of wastewater from a shallow reservoir to an underground reservoir is done using gravi ty-driven flow through a smooth-walled pipe (see diagram below). In order to control the flow, the diameter is reduced slightly between the top and vertical sections of the pipe (a simple practical ap plication of the Bernoulls equation). The smooth walls of the pipe generate very little shear, so that the flow follows the Bernoulli equation very nearly exactly. You may neglect pressure losses...

(c) Fuel oil, with a density of 870 kg m-, is pumped through a horizontal pipe, as shown in Figure Q2.2. The pipe is 100 mm in diameter and contains an orifice plate with a throat diameter of 40 mm. The pressure drop across the orifice is measured on a U-tube manometer, containing mercury with a specific gravity 13.6. The difference in levels of the columns is measured as 45 mm. The coefficient of discharge for the orifice plate Ca...
