Unit Conversion

Standard units are also called SI units. SI units are used for measuring a physical quantity satisfying certain conditions. There are two types of units: fundamental units and derived units. Fundamental units are physical quantities that are independent, that is, they do not depend on other quantities like mass, length, or time. There are plenty of quantities in our lives which need to be measured and compared. Measuring is the comparison of a particular physical quantity with its reference value. A unit is a measure of a fixed physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.

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.
