5. Calculate the frictional pressure drop for a 50 % solution of glycerol with a density of 1.1273 g/cc and a viscosity of 7.1 cP at 18°C through an elliptical duct made from galvanized iron (ɛ = 0.152 mm) having an internal dimension of 0.8 m at its widest point and 0.3 m at its highest point and a total length of 4 meters at a rate of 2,500 lbm/s. (Use equation 6-37 of Perry's Handbook (9th edition) to calculate for fanning friction factor).
Kinetic Theory of Gas
The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all directions. It also says that the constituent particles/molecules undergo elastic collision, which means that the total kinetic energy remains constant before and after the collision. The average kinetic energy of the particles also determines the pressure of the gas.
P-V Diagram
A P-V diagram is a very important tool of the branch of physics known as thermodynamics, which is used to analyze the working and hence the efficiency of thermodynamic engines. As the name suggests, it is used to measure the changes in pressure (P) and volume (V) corresponding to the thermodynamic system under study. The P-V diagram is used as an indicator diagram to control the given thermodynamic system.
