Question

Optimum Compression ratio for maximum specific output for ideal gas (air) turbine plant operating at initial temperature of 290K and maximum temperature of 1000K, is closure to

Answer 1

The correct answer is 21.94

Explanation:

We can find out the Optimum Compression ratio for maximum specific output for ideal gas (air) turbine plant operating at initial temperature of 290K and maximum temperature of 1000K as follow

η=1-1/rk-1      

we know that  

η= 1- T2/T1

So,  

1-T2/T1= 1-1/rk-1      

Then,  

1-(290/1000)= 1/r1.4.1

So, we get  

r= 21.94

Since, we know that r= compression ratio, Hence the answer is 21.94

Also, it is a ratio so it is unitless quantity
