Compared to a turbo- jet engine, a turbo- prop engine has a higher power for take – off

Question

 

Direction: Each of the next consists of two statements, one labeled as the ‘Assertion (A)’ and the other as carefully and select the answers to these item using the codes given below:

1. Both A and R are indidually true and R is the correct explanation of A
2. Bothe A and R are individually true but R is not the correct explanation of A
3. A is true but R is false
4. A is false but R is true

Assertion (A):  Compared to a turbo- jet engine, a turbo- prop engine has a higher power for take – off and higher propulsive efficiency at low speeds

Reasons (R):  By mounting the propeller on the turbine shaft, the propeller can be run at a very high speed to obtain higher efficiency.
