Question

What is relative pressure at 1600ft? (P1600=95602 N/m^2)

(a) 0.9453

(b) 0.9858

(c) 0.9435

(d) 0.9595

I have been asked this question during an online interview.

I'd like to ask this question from Standard Atmospheric Model in chapter Atmosphere and Air Data Measurement of Aircraft Performance

Answer 1

Right option is (c) 0.9435

The best I can explain: The answer is 0.9435.

Given P1600=101325 N/m^2,

From relative pressure (δ)=\(\frac{P_{1600}}{p_0}\)

δ=\(\frac{95602}{101325}\)=0.9435.
