Answer:
investor claim is acceptable
Explanation:
given data
Win = 0.25 kW
Qc = 3000 J/s = 3kW
Th = 293 K
Tc = 270 K
solution
we get here coefficient of performance of cycle is
coefficient of performance = ..................1
put here value and we get
coefficient of performance =
coefficient of performance = 1.2
and
coefficient of performance of ideal refrigeration is
coefficient of performance = ..................2
coefficient of performance =
coefficient of performance = 11.74
and
we can see here that coefficient of performance of ideal refrigeration is is more than real cycle coefficient of performance
so investor claim is acceptable

Rate of water = 0.26 ft^3/s
Applying bernouli equation on bioth side
.....1
where P_2 = 182 psi
P_1 = 0, v_1 = 0
calculation fro friction factor
from standard table we have
so for calculated R and, F value = 0.0212
from equation 1
h_p = 826.76ft so that
