3-stage compressor Flashcards
1
Q
Conditions for minimum work
A
W_LP = W_IP = W_HP
T5 = T3 = T1
2
Q
Analysis of Three stage compressor in terms of Pressure
A
Px/P1 = Py/Px = P6/Py
3
Q
Pressure at intercooler 1, Px
A
`Px = sqrt(P1^2 * P6)
4
Q
Pressure at intercooler 2, Py
A
Py = sqrt(P1 * P6^2)
5
Q
Work of Compressor, Wc
A
W_LP + W_IP + W_HP
6
Q
W_LP
A
(nP1V1’)/(n-1) [(Px/P1)^(n-1)/n - 1]
7
Q
W_IP
A
(nP3V3’)/(n-1) [(Py/Px)^(n-1)/n - 1]
8
Q
W_HP
A
(nP5V5’)/(n-1) [(P6/Py)^(n-1)/n - 1]
9
Q
IDEAL WORK, Wc
A
(3nP1V1’)/(n-1) [(Px/P1)^(n-1)/n -1]
(3nP1V1’)/(n-1) [(P6/P1)^(n-1)/3n - 1]
10
Q
Volume Displacement, V_D
A
LAN
where:
A = π/4 [D_LP^2 - D_HP^2]
