Vapour compression refrigeration cycle using ammonia as refrigerant has a capacity of 30 TR . Evaporator and condenser temperatures are

-16\deg C

and

50\deg C

respectively. Ammonia enters the compressor in dry saturated state and leaves the condenser after complete liquefaction. Specific heat of ammonia vapour is

2.3k(J)/(k)gK

. Sketch the cycle on

T-s

and

P-h

plots and Calculate the following: (a)Max. COP of the System (b)Mass flow rate of ammonia in

k(g)/(h)r

(c)Power supplied to compressor in kW (d) Heat Rejected in Condenser in kW

Which of the following are TRUE?
Choose ALL the correct answers.
\sqrt((4n^(2)-n)/(n^(2)+1))=\sqrt((4-(1)/(n))/(1+(1)/(n^(2))))
\sqrt((4n^(2)-n)/(n^(2)+1))=(2n-\sqrt(n))/(n+1)
\sqrt((4n^(2)-n)/(n^(2)+1))=(\sqrt(4n^(2)-n))/(\sqrt(n^(2)+1))
\sqrt((4n^(2)-n)/(n^(2)+1))=\sqrt(4-n)
