4. Using the Hazen-Williams nomograph determine the following: a. The head loss as 5.6 liters/s of water flows through a 24.38 m length of 64 mm cast iron water main pipe. b. The diameter of cast iron pipe that can carry 19 liters/s over a length of 366 m with no more than a 3 m head loss. C. Compare the head loss that would result from the flow of 6.5 liters/s of water through 305 m of cast iron pipe for 50 mm and 75 mm diameter pipe sizes.

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.
