Dep. 4th Year Students Final Examination (2022-2023) Subj.: Process of unit operation Date: 6/6/2023 Time: 3 Hours: Morning & Evening Study Note/Answer only four questions, including the first question Q.1: Water is to be cooled in a packed tower from 330 to 295 K by means of air flowing counter currently. The liquid flows at the rate of 275 cm³/m² s and the air at 0.7 m³/m² s. The entering air has a temperature of 295 K and a humidity of 20%. Calculate the required height of tower and the condition of the air leaving at the top. The whole of the resistance to heat and mass transfer can be considered as being within the gas phase and the product of the mass transfer coefficient and the transfer surface per unit volume of column (ha) may be taken as 0.2 s¹. Assuming, the latent heat of water at 273 K = 2495 kJ/kg, specific heat capacity of dry air = 1.003 kJ/kg K, specific heat capacity of…

It shows the four basic steps in a 4-stroke internal-combustion engine that are usually found in cars. Based upon what you have learned, explain why, in the 3rd step, the explosion forces the piston down.

View Policies Current Attempt in Progress A High-Performance Engine. You and your team are tasked with evaluating the parameters of a high-performance engine. The engine compresses the fuel-air mixture in the cylinder to make it ignite rather than igniting it with a spark plug (this is how diesel engines operate). You are given the compression ratio for the cylinders in the engine, which is the ratio of the initial volume of the cylinder (before the piston compresses the gas) to the final volume of the cylinder (after the gas is compressed): VV, Assume that the fuel-gas mixture enters the cylinder at a temperature of 26.0 °C, and that the gas behaves like an ideal gas with y-7/5. (a) If the compression ratio is 14.9:1, what is the final temperature of the gas if the compression is adiabatic? (b) With everything else the same as in (a). what is the final temperature of the gas if the compression ratio is increased to 16.117 (c) Everything else being the same, for which compression ratio…
