Dry air at `15^0 C` and 10 atm is suddenly released at atmospheric pressure. Find the final temperature of the air `[C_p / C_v = 1.41]`.

Text Solution

Verified by Experts

As the air is suddenly released, it does not get
time to exchange heat with the surrounding. Thus the
process is adiabatic. Assuming the process to be reversible,
`T^gamma / P gamma^(-1)` = constant
or, `T_1^gamma / P_1 gamma^(-1)` = T_2 gamma / P_2 gamma (-1)`
or `(T_2 / T_1)gamma = ( P_2 / P_1) gamaa ^(-1)`
or, `T_2 = T_1 (P_2/ P_1)gamma^(-1)/gamma.

We often have the experience of pumping air into bicycle tyre using hand pump. Consider the air inside the pump as a thermodynamic system having volume V at atmospheric pressure and room temperature, 27^(@)C . Assume that the nozzle of the tyre is blocked and you push the pump to a volume 1//4 of V. Calculate the final temperature of air in the pump? (For air, since the nozzle is blocked air will not flow into tyre and it can be treated as an adiabatic compression). Take gamma for air = 1.4
