The Correct Option is D
Solution and Explanation
Step 1: Recall the function of the casing.
The impeller imparts velocity to the air, producing velocity pressure.
Step 2: State the role of the casing. The volute casing gradually increases the flow area, reducing air velocity and converting velocity pressure into static pressure. Hence, \[ \boxed{\text{Casing}} \] is the correct answer. Therefore, \[ \boxed{(D)} \] is the correct answer.
Step 2: State the role of the casing. The volute casing gradually increases the flow area, reducing air velocity and converting velocity pressure into static pressure. Hence, \[ \boxed{\text{Casing}} \] is the correct answer. Therefore, \[ \boxed{(D)} \] is the correct answer.
