With respect to lakes (a) describe using a diagram what is meant
by thermal stratification and (b) using diagrams differentiate
between typical benthic and pelagic food webs.
a.) What is the thermal efficiency of a steam power plant
operating on the Rankine cycle if saturated steam is supplied to
the turbine at 1000 psia, and the condenser is at 1 psia. Use a
turbine efficiency of 95% and a pump efficiency of 85%. Refer to
Chapter 9, Sections 10-11, as necessary.
b.) Determine the thermal efficiency if the steam is superheated to
1000 F, assuming all else equal.
Explain what is meant by the Fisher Separation Theorem (FST).
Graphically demonstrate FST for the case where an individual ends
up lending in financial markets.
Graphically analyse the effect of an increase in the
interest rate on the utility of lenders. Discuss whether or not the
lenders are better off as a result of the interest rate
rise.
Critically evaluate the assumptions upon which the
Fisher Separation Theorem is based and assess the extent to which
these limit its usefulness...
Write short notes on the essential differences and underlying
causes in the thermal and mechanical properties of polymers,
metals, and ceramics.
*very simply..!! Thank you
Write short notes on the essential differences and underlying
causes in the thermal and mechanical properties of polymers, metals
and ceramics (25pts)
Please answer correclty, neat and enough for 25 points question,
thumbs up
1. Write an introduction about the thermal and
mechanical properties of stainless steel and how it is suited to
the construction industry
2. Write an introduction about the fire testing in
stainless steel
3. identify problems situated to stainless steel e.g.
cost etc
4. Write up a scope based on this topic
Please list the principal determinants of capital investment?
Explain what is meant by the "marginal efficiency of capital." What
is its role in determining the present value of an investment? Why
is investment commonly a discrete, non-continuous function with
respect to interest rates? Distinguish among the main ways by which
firms finance investment. Explain the accelerator principle. In
what ways does the timing of expected returns to investment
determine the level and composition of spending on productive
capital.
