Question

PLEASE ANSWER IN TYPEWRITTEN AND CORRECT ANSWER

SUBJECT: FLUID MECHANICS FOR CIVIL ENGINEERS

1. A horizontal pipeline reduces from 190 mm diameter to 70 mm diameter. Water
enters the pipe at 3.6 m/s and 350 kPa gauge. For the 70 mm diameter output,
calculate:
(a) velocity
(b) pressure
(c) pressure head
(d) velocity head
2. A pipe carrying a chemical solvent reduces from 80 mm diameter to 55 mm
diameter. The pressure is measured at the larger diameter as 10.22 kPa gauge and
at the small diameter as 7.65 kPa gauge. If the mass density of the chemical is 790
kg/m³, calculate the volume flow rate.
3. A pump is used to collect water from an underground tank. The tank water level is
5.44 metres below the pump and the flow is 25.5 litres per second through a 75 mm
diameter pipe. Calculate the pressure at the pump inlet.
4. Horizontal pipe of 150 mm diameter discharges 60 kg/s of an oil of relative
density of 0.89. At a point in the pipe, the pressure is 120 kPa gauge. Calculate the
pressure head and the velocity head at the point.
