Q1
a) Company A designed a heat pump to
supply heat into a library in Canada during
winter, so that the library can maintain to be at 20°C. The heat
pump utilizes
12,000 L/min of Refrigerant-134a as the working fluid and absorb
heat from an
industrial water stream. The water stream enters the evaporator at
50°C and exits
at 25°C. The refrigerant enters the evaporator at 10°C with 90%
moisture content
and leaves at 20°C. There is no pressure drop in...

Use the following information to complete steps (a) through (d) below. A random sample of ny = 135 individuals results in xy = 40 successes. An independent sample of n2 = 150 individuals results in x2 = 60 successes. Does this represent sufficient evidence to conclude that P, <P2 at the a = 0.10 level of significance? (a) What type of test should be used? A. A hypothesis test regarding the difference between two population proportions from independent samples. B....

The z-test 10.1 Assume that a treatment does have an effect and that the treatment effect is being evaluated with a z hypothesis test. If all factors are held constant, how is the outcome of the hypothesis test influenced by sample size? To answer this question, do the following two tests and compare the results. For both tests,...

Saturated liquid water at a pressure of P before entering the CFWH. 12 kPa is pumped to a pressure of Pi-5 MPa After leaving the CFWH as a saturated liquid, the water continues to a Steam Generator which heats the water to a temperature of Ts 600°C. This superheated steam is used to drive a Turbine. A quantity...
