Question:-
Match List I with list II and select the correct answer :
List I (Cycles operating between fixed temperature limits)
A. Otto cycle
B. Diesel cycle
C. Carnot cycle
D. Brayton cycle
List II (Characteristic of cycle efficiency h temperature)
1. h depends only upon temperature limits
2. h depends only, on pressure limits
3. h depends on volume compression ratio
4. h depends on cut-off ratio and volume compression ratio
Option (A)

A B C D
3 4 1 2

Option (B)

A B C D
1 4 3 2

Option(C)

A B C D
3 2 1 4

Option(D)

A B C D
1 2 3 4

Correct Option:
(A)
Question Solution:
Otto cycle
hottot = 1 –(1/(r)r-1)
r = compression ratio = (v1/v2)
l = specific heat ratio = (cp/cv)
Diesel Cycle
hdisesel = 1 –(1/(r)l-1 [(rrc-1)/ l(rc-1)]
Where
r = compression ratio = v1 /v2
rc = cut off ratio = v3/v2
Brayton cycle
hbrayton = 1-(1/(rpl-1/r))
Where
rp = pressure ratio = P2/P1
Carnot Cycle
hcarnot = 1-(T2/T1
T2 = higher temperature
T1 = lower temperature
