As a part of a maintenance inspection the compressor of a jet engine is made to spin according to the graph as shown. Find the number of revolutions made by the compressor during the test?

A

9000

B

16570

C

12750

D

11250

Text Solution

Verified by Experts

The correct Answer is:
D
No. of revolution = angular displacement
= area under `omega-t` graph
= `(1)/(2)(2.5+5)xx3000`
= `11250` rev .
