Answer to Problem 1E

The combustion is a highly irreversible process.

Explanation of Solution

Combustion reactions are usually known as an irreversible process. It takes place when any specific fuel burns. During combustion reaction, an organic species containing the mixture of hydrogen and carbon atoms gets reacted with oxygen to give water and carbon dioxide. Here, carbon and hydrogen acts as reactants and water and carbon dioxide are products of the combustion reaction.

The combustion process cannot call as reversible process since conversion of carbon dioxide to hydrocarbons takes infinity period of time.

Hence, the combustion is a highly irreversible process.

A pump delivering 230 lps of water at 30C has a 300-mm diameter suction pipe and a 254-mm diameter discharge pipe as shown in the figure. The suction pipe is 3.5 m long and the discharge pipe is 23 m long, both pipe's materials are cast iron. The water is delivered 16m above the intake water level. Considering head losses in fittings, valves, and major head loss. a) Find the total dynamic head which the pump must supply. b)It the pump mechanical efficiency is 68%, and the motor efficiency is 90%, determine the power rating of the motor in hp.
The tensile 0.2 percent offset yield strength of AISI 1137 cold-drawn steel bars up to 1 inch in diameter from 2 mills and 25 heats is reported as follows: Sy 93 95 101 f 97 99 107 109 111 19 25 38 17 12 10 5 4 103 105 4 2 where Sy is the class midpoint in kpsi and fis the number in each class. Presuming the distribution is normal, determine the yield strength exceeded by 99.0% of the population. The yield strength exceeded by 99.0% of the population is kpsi.
