ideal gas model has many applications in engineering practice and is frequently used in subsequent section of this text. Ideal gas Equation state From the Generalized compressibility chart show that the state where the pressure p is small relative critical pressure Pc (low PR)‚ and the temperature T is large relative to the critical temperature Tc (high Tc ). The compressibility factor Z =Pv/RT ‚ is approximately. At such state we can assume with reasonable accuracy that Z=1‚ or: Pv

earth’s surface oceans and life in general. Atmosphere The envelope of gases that surround a planet and are held to it by the planet’s gravitational attraction. The earth’s atmosphere is mainly Nitrogen and oxygen. Layers of the atmosphere: Air pressure and density decrease with height above the earth‚ rapidly at first‚ then more slowly. Air temperature has however‚ more complicated vertical profile. Air temperature

`A 20cm diameter pipe of length 100m with z = 60m with f = 0.02 and loss of head due to entrance coefficient k = 0.5. What is the flow rate? Solution: Find the width in m of the channel at the back of a suppressed weir using the following data: H = 28.5cm; d = 2.485m; Q = 0.84 cu.m/sec. Consider the velocity of approach and use the Francis formula. Solution: Water flows in a 2m. wide rectangular flume at the rate of 2.75 cu.m./sec
