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
Number of revolution = Area between the graph and time axis = Area of trapezium
`= (1)/(2)xx(2.5+5)xx3000=11250` revolution.
