Explanation:
The frictional resistance of the various pipes are given by the
K value in the table which may be used with the formula
hf = KQ2
to relate the magnitude of head loss hf in the pipeline
to the volumetric flow rate, Q. Water is drawn at the constant flow
rates from the network at nodes C and D. The static heads
(elevation + pressure head) at nodes B, C and D are 100m, 65m
and 61m respectively above the local datum. Calculate the
discharges at C and D and the water level in reservoir A. (The
data has been added to the diagram to aid the solution)
Use no more than 3 iterations and 3 significant figures.
A would be the right choice i think not really enough information.
Answer: 1.9%
Explanation:
First derive the Market return as this is needed in the Capital Asset Pricing Model by using the same model:
Required return = Risk free rate + Beta * ( market return - Risk free rate)
Using stock Y:
12.4% = Risk free rate + 1 * (market return - Risk free rate)
12.4% = Rf + market return - Rf
Market return = 12.4%
Use this to calculate the Risk free rate:
Stock Z:
8.2% = Rf + 0.6 * (12.4% - Rf)
8.2% = Rf + 7.44% - 0.6Rf
Rf - 0.6Rf = 8.2% - 7.44%
0.4Rf = 0.76%
Rf = 0.76% / 0.4
= 1.9%
