A brass pipe has an internal diameter of400mm and a metal thickness of6mm. A triple layer ofbigh tensile wire ofdiameter 3 mm is wound closely round it at a tension of500 N. Find (a) the stress in the pipe when there is no internal pressure; (b) the maximum permissible internal pressure in the pipe if the working tensile stress in the brass is 60 MNhn2 ; (c) the stress in the steel wire under condition O). Treat the pipe as a thin cylinder and neglect longitudinal stresses and strains. E, = 200GN/m2; Erl OOGN/m:

A copper pipe of diameter 3.5 cm and wall thickness 4 mm is used in an antibiotic factory to convey hot water a distance of 60 m at a flow rate of 20 L/s. The inlet temperature of the water is 90°C. Due to heat losses to the atmosphere, the outlet water temperature is 84°C. The ambient temperature is 25°C. The inside of the pipe is covered with a layer of fouling with a fouling factor of 7500 W/m2°C. What...

A horizontal pipe of diameter 0.768 m has a smooth constriction to a section of diameter 0.4608 m. The density of oil flowing in the pipe is 821 kg/m3 . If the pressure in the pipe is 7120 N/m2 and in the constricted section is 5340 N/m2 , what is the rate at which oil is flowing? Answer in units of m3/s.

Crude oil of specific gravity (0.75) is flowing through a pipe. The pipe has a diameter of 100 mm and 50 mm at the sections 1 and 2 respectively. The velocity of crude oil at the section 1 is 550 cm/s. The section 1 is 3000 mm and section 2 is 2000 mm above the datum. If the pressure at the section 1 is 0.2 N/mm2, find the intensity of pressure at section 2?

Crude oil of density 970 kg.m-3 flows in a pipe of internal diameter 9 inches and circular section that exhibits a 90° bend in the horizontal plane. The flowrate of the oil is 11,000 litres per minute. Calculate the force imparted by the oil on the bend due to the change of momentum of the fluid, and draw a diagram to indicate the direction of this force.

1200 cm3/sec of water at 420 K is pumped in a 40 mm internal diameter pipe through a length of 150 m in a horizontal direction and up through a vertical length of 10 m . In the pipe there is a control valve which may be taken as equivalent to 200 pipe diameters and other pipe fittings equivalent to 60 pipe diameter. Also in the line there is a heat exchanger across which there is a loss in head...
