Answer:
1/2 or 1:2
Explanation:
first convert speed of compressor to rpms
Compressor speed= w1 = 150 cycles/s= 150 * 60= 9000 rpms
Speed of turbine= w2 = 18000 rpms
gear ratio = N2/N1 = w1/w2
gear ratio = 9000/18000
gear ratio = 1/2
gear ratio = 1:2

Answer:
9.248 < < 9.253 mm
Explanation:
Given data:
standard deviation = 0.021 mm
sample mean = 9.251 mm
total sample = 409 m
confidence interval level = 95%
mean diameter of entire batch
where
- sample mean = 9.251 mm
z = critical value
plugginf all value in the above relation to get the mean diameter
9.248 < < 9.253 mm
