Aspace shuttle moves through the atmosphere on its return from space. at point 1 on its wing, the air temperature and pressure are measured to be t1 = 300°c and p1 = 10,000 pa while at point 2 they are t, = 700°c and p2 = 575,000 pa. calculate the air density in kg/m3 at both points 1 and 2.

The air density in at points 1 is and 2 is .

Explanation:

Average molecular weight of an air ,M= 28.97 g/mol

or

P = Pressure of the gas

n = moles of gas

T = Temperature of the gas

d = Density of the gas

M = molar mass of the gas

R = universal gas constant

Density at point-1 =

M = 28.97 g/mol

1 g = 0.001 kg

Density at point-2 =

M = 28.97 g/mol
