A stationary diesel engine with a thermal efficiency of 40% produces 200 horsepower. The exhaust gas, which we suppose is air, has a velocity of 1400 R, whereas the intake has a velocity of 520 R. What is the mass flow rate if it accounts for half of the QL?

Design of Shafts and Shaft Components

The shaft is basically defined as the machine element that rotates, is in circular cross-section, it is majorly used to transfer the power from one part of the system to another, or from a power generating machine to a power absorbing machine. The shaft is supported on bearings and is rotated with the help of a set of gears or pulleys that are used for the power transmission. Bending moment, torsion, and an axial force act upon the shaft. Designing of shaft primarily involves determining stresses at a critical point in the shaft that is arising due to loading.
