A 2.5 TR split unit is to be powered using solar photovoltaic (PV) cells. Assume the cooling unit has a COP = 3, the solar panel converts only the direct solar radiation (i.e. neglect diffuse part) & the conversion energy efficiency is 30%, calculate the required surface solar panel area (m2) and the saving in the monthly running cost (S.R./month) assume 8 hr’s unit daily operation & the power charge is 0.18 S.R/kW-hr. To calculate the solar radiation, use the following data: Location: Jeddah, l = 21.67o, L = 39.15o, CN = 0.7 Day: June 21st Solar hour (h) = 37.6o the solar panel is facing south with a surface tilting angle = 23o from the horizontal.

A wood burning stove is box shaped with a height of 30.7”, width 26.25” and depth 25.5”. The front surface is glass (Ԑ= 0.9) and the other surfaces are cast iron (Ԑ= 0.7). The fire keeps the stove surface at a constant 202 °C.

a.Calculate the rate at which the stove’s one glass surface (30.7” by 26.25”) radiates heat into the surrounding space.

b.Calculate the rate at which the cast iron sides radiate heat into the surrounding space. Add this to your answer to part a) to determine the total rate of radiation into the surrounding space. Assume the stove is raised off the floor so the bottom radiates.

c. If the surrounding temperature is 22 °C, find the net rate of radiative heat transfer from the wood stove to the surroundings

Intermediate Macroeconomic Question.

1. Given that the money supply is 1400, consumption equation is represented as:

C = 120 + 0.7 (Y-T),

investment equation is I=200-10r, where r is the real interest rate while Taxes (T) and Government expenditure are 200 and 400 respectively. The real money demand function is expressed as m/p=0.1y -100r (units in million)

i) Solve for equilibrium real output and equilibrium interest rate

ii) Assume that autonomous investment increases by 300, compute the investment multiplier and analyze the new impact on income and consumption.

b) Use the Mundell- Fleming to show that under perfect mobility and flexible exchange rates, fiscal policy is ineffective.

c) Discuss the key assumptions of the Mundell - Fleming model.

Let x = red blood cell (RBC) count in millions per cubic millimeter of whole blood. For healthy females, x has an approximately normal distribution with mean μ = 3.5 and standard deviation σ = 0.7. Express answers to 2 decimal places.

(a) Convert the x interval, x > 4.5, to a z interval.
z >  

(b) Convert the x interval, x < 4.2, to a z interval.
z <  

(c) Convert the x interval, 4.0 < x < 5.5, to a z interval.
< z <  

(d) Convert the z interval, z < –1.44, to an x interval.
x <  

(e) Convert the z interval, z > 1.28, to an x interval.

An oil exploration company currently has two active projects, one in Asia and the other in Europe. Let A be the event that the Asian project is successful and B be the event that the European project is successful. Suppose that A and B are independent events with P(A) = 0.7 and P(B) = 0.4.

(a) If the Asian project is not successful, what is the probability that the European project is also not successful?

Explain your reasoning.

Since the events are independent, then A' and B' are not independent. Since the events are not independent, then A' and B' are mutually exclusive.     Since the events are independent, then A' and B' are independent, too. Since the events are independent, then A' and B' are mutually exclusive.

(b) What is the probability that at least one of the two projects will be successful?


(c) Given that at least one of the two projects is successful, what is the probability that only the Asian project is successful?

In a test of the effectiveness of garlic for lowering​ cholesterol, 36 subjects were treated with raw garlic. Cholesterol levels were measured before and after the treatment. The changes​ (before minus​ after) in their levels of LDL cholesterol​ (in mg/dL) have a mean of 0.7 and a standard deviation of 20.1. Use a 0.10 significance level to test the claim that with garlic​ treatment, the mean change in LDL cholesterol is greater than 0. What do the results suggest about the effectiveness of the garlic​ treatment? Assume that a simple random sample has been selected. Identify the null and alternative​ hypotheses, test​ statistic, P-value, and state the final conclusion that addresses the original claim. What are the null and alternative​ hypotheses?

Determine the test statistic.

Determine the​ P-value.

1.14. A service facility consists of two servers in series (tandem), each with its own FIFO
queue (see Fig. 1.50). A customer completing service at server 1 proceeds to server 2,
while a customer completing service at server 2 leaves the facility. Assume that the
interarrival times of customers to server 1 are IID exponential random variables with
mean 1 minute. Service times of customers at server 1 are IID exponential random
variables with mean 0.7 minute, and at server 2 are IID exponential random variables
with mean 0.9 minute. Run the simulation for exactly 1000 minutes and estimate for
each server the expected average delay in queue of a customer, the expected time-
average number of customers in queue, and the expected utilization.
