How can the temperature of the incoming air affect the effect of the gas turbine? Describe this by drawing a T-s diagram. Also draw a T-s diagram for how the compression ratio affects the effect and a T-s diagram for how the combustion temperature affects the effect.

Air enters the turbine of a gas turbine at 1400 kPa, 1400 K, and
expands to 100 kPa in two stages. Between the stages, the air is
reheated at a constant pressure of 350 kPa to 1400 K. The expansion
through each turbine stage is isentropic.
Determine:
(b) the heat transfer for the reheat process, in kJ/kg of air
flowing.
(c) the increase in net work as compared to a single stage of
expansion with no reheat.

In a gas turbine of a thermoelectric plant a regenerator is used
that preheats the air before it enters the combustion chamber. You
have the options of a backflow heat exchanger or a shell heat
exchanger and two tube passages. The air leaves the compressor at a
temperature of 350 C and the exhaust gases have a temperature of
700 C. The mass flow in both cases is 5 kg / sec. The overall
transfer coefficient is 75 w /...

A gas turbine operates as a cold-air standard Brayton cycle. Air
enetrs the compressor at 300K and 100kPa and is compressed to
700kPa. During the heat addition process in the combustor, the
temperature of the air increases to 1000K. The turbine and
compressor can be assumed to be operating isentropically. Evaluate
specific heat at 300K.
a. thermal efficiency of the cycle?
b. net work of the cycle (kj/kg)?
c. Back work ratio?

An adiabatic gas turbine uses air to produce work. Air expands
adiabatically from 600 kPa and 287 C to 90 kPa and 67 C. Take
specific heats at room temperature (300 K). a) Find the isentropic
efficiency of the turbine. b) Find the work produced by the turbine
for a mass flow rate of 2.5 kg/s. c) If the mass flow rate of air
is again 2.5 kg/s, find the entropy generation under steady
conditions

. In a gas turbine plant, air enters a compressor at atmospheric
conditions of 15 ?C, 1.0133 bar and is compressed through a
pressure ratio of 10. The air leaving the compressor passes through
a heat exchanger before entering the combustion chamber. The hot
gases leave the combustion chamber at 800 ?C and expand through an
HP turbine which drives the compressor. On leaving the HP turbine
the gases pass through a reheat combustion chamber which raises the
temperature of...

A
gas turbine operates with two stages of compression with an
intercooler between the stages. Air enters the first stage at 100
kPa and 300 K. The pressure ratio across each compressor stage is 5
to 1 and each stage has an isentropic efficiency of 85%. Air exits
the intercooler at 330 K. The maximum cycle temperature is 1500 K
and the cycle has a single turbine stage that works isentropically.
