Temperature
EXAMPLE 1: A diesel engine is fitted with a turbocharger,
which comprises a radial compressor driven by a radial
exhaust gas turbine. The air is drawn into the compressor at
a pressure of 0.95 bar and at a temperature of 15°C, and
is delivered to the engine at a pressure of 2.0 bar. The
engine is operating on a gravimetric air/fuel ratio of 18: 1,
and the exhaust leaves the engine at a temperature of
600°C and at a pressure of 1.8 bar; the turbine exhausts at
1.05 bar. The isentropic efficiencies of the compressor and T(K)
turbine are 70 per cent and 80 per cent, respectively.
Calculate (i) the temperature of the air leaving the
compressor (ii) the temperature of the gases leaving the
turbine (iii) the mechanical power loss in the turbocharger
expressed as a percentage of the power generated in the
turbine. Using the values of : Cpair = 1.01 kJ/kg K, Vair = 1.4
Cpex = 1.15 kJ/kg K, Yex = 1.33

■Review
The uniform crate resting on the dolly has a mass of 530 kg and
mass center at G as shown in (Figure 1).
If the front casters contact a high step, and the coefficient of static friction between the crate and the dolly is μs = 0.45, determine the greatest force P that can be
applied without causing motion of the crate. The dolly does not move.
Express your answer to three significant figures and include the appropriate units.

A task force has been formed to address this issue, and you have been assigned a critical role in developing a damping control strategy. Your objective is to analyze system performance, propose engineering solutions, and compare the effects of different damping approaches. Answer the following questions 1. Identify the Engineering Problem: - What is the fundamental issue affecting power grid stability? - How do low-frequency oscillations impact the system's reliability? - What parameters indicate system instability? 2.
