28. A high-pass filter passes signals with frequencies
that are higher than a certain cutoff frequency
In this filter the ratio of the magnitudes of the
voltages is given by:
R3
LEWRC
TIRE
where w=21ſ is the frequency of the input signal. Given R = 2,000 and
C =0,2 uF plot as a function of ſfor 10 <1 < 50,000 Hz. Use logarith-
mic scale for the horizontal (l) axis and linear scale for the vertical axis.
Note: mis labeled as “frequency" in the text, it is the angular frequency or angular
velocity in rad/s (o = 2nf where fis frequency in Hz).
Tips: 1. Use f-[10:10:50000]
2. 1 uF = 1.0e-6 F

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
