If at 70 degrees the PSI is 1800, then what is the PSI at 29 degrees?

Answer 1

Hi Deb

If at 70 degrees the PSI is 1800, then what is the PSI at 29 degrees?

Given: 70 degrees PSI 1800

Find: 29 degrees PSI = ?

Assumptions: I'm going to assume since you only have Temp and Pressure, the volume remains the same.

I would use the equation:

P₁V₁/T₁ = P₂V₂/T₂

Since the Volume is constant you would get

P₁/T₁ = P₂/T₂

1800 PSI / 70 degrees = P₂ / 29 degrees

P₂ = 746 PSI
