Answer:

False

Explanation:

The two most important fields of expertise for their career were not defined as architecture and mathematics by architects.

It offers expertise and expertise to architects and engineers that can not be gained by practicing alone.

The useful work potential of energy is called: a. Exergy b. Power c.Equilibrium d. Reversible work

tia_tia [17]

Answer:

a) Exergy

Explanation:

The useful work potential is called exergy. All practical process are ir-reversible process due to ir-reversibility ,the entropy of system increases and this leads to destroy the energy.

The rate of work is called power.

Reversible work is the maximum obtain work potential because it have all processes reversible.

So from this our option a is right.

What is the thermal efficiency of this reheat cycle in terms of enthalpies?

schepotkina [342]

Answer:

$\eta =\dfrac{\left (h_3-h_4\right )+(h_5-h_6)-(h_2-h_1)}{(h_3-h_2)+(h_5-h_4)}$

Explanation:

For close gas turbine:

Gas turbine works on Brayton cycle.Gas turbine have lots of applications like ,it is use in aircraft,in land applications etc.

Reheating is the method to improve the efficiency of the gas turbine.In reheating gas is expanding in two turbine instead of one turbine alone.Two turbine like high pressure turbine and low pressure turbine are used for expansion.

In the above diagram 1-2 is a compressor,2-3 heat addition,3-4 high pressure turbine,4-5 reheating of cycle 5-6 low pressure turbine,6-1 heat rejection,

We know that $\eta =\frac{W_{net}}{Q_{s}}$
