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.

Problem 4
Pipe Flow and Moody's
A farmer is to pump water at 70°F from a river to a water storage tank nearby using a 125-ft-
long, 5 in diameter galvanized iron with three (3) flanged 90° smooth elbows and one (1) sharp-
edged exit. The water velocity near the river surface is 6 ft/s, and the pipe inlet is placed in the
river normal to the flow direction of water to take advantage of the dynamic pressure. The tank
is also open to the atmosphere and the river is open to the atmosphere. The elevation
difference between the river and the free surface of the tank is 12 ft. For a flow rate of 1.5 ft³/s
and an overall pump efficiency of 70 percent. Determine the required electric power input to the
pump. The density and dynamic viscosity (u) of water at 70°F are p = 62.30 lbm/ft³ and μ =
6.556x104 lbm/ft.s.
