The tutor looks more specifically into the effect of compression on gas temperature.

In my January 20 post I began about thermodynamics and the effect of compressing a gas. Today, I’ll give more specific coverage.

The temperature rise a gas experiences (without change in entropy) due to pressure is given by the formula

T₂ = T₁(P₂/P₁)^[1-1/γ]

where

T₁,T₂ are initial and final temperatures

P₁,P₂ are initial and final temperatures

γ = C_p/C_v, where

C_p = gas specific heat at constant pressure

C_v = gas specific heat at constant volume

Typcially, γ might be around 1.4. Therefore, imagining a diesel engine with 17:1 compression, at starting temperature 298K (25°C) the resulting temp, T₂, might be

T₂=298(17/1)^[1-1/1.4]

T₂=670K
