Answer:
The value of heat transfer during the process Q = - 29.49 KJ
Explanation:
Given data
= 50
= 344.7 k pa
= 0.113
F = 366.4 K
= 477.6 K
Poly tropic index n = 1.2
gas constant for oxygen = 0.26
From ideal gas equation
= m R
Put all the values in above equation we get
⇒ 344.7 × 0.113 = m × 0.26 × 366.4
⇒ m = 0.408 kg
Heat transfer in poly tropic process is given by
Q =
Put all the values in above formula we get
⇒ Q =
⇒ Q = 2.5 × 0.408 × 0.26 × ( 366.4 - 477.6 )
⇒ Q = - 29.49 KJ
This is the value of heat transfer during the process & negative sign shows that heat is lost during the process.
