Calculate Hydraulic Pump Power and Shaft Pump Power ?

An N-Channel device has K’n = 50 µA / V^2, Vt = 0.8 V and W/L = 20. The device is operating as a switch for small Vds, utilizing a control voltage Vgs in the range 0 V to 5 V. Find the switch closures resistance, Rds and closure voltage, Vds obtained when Vgs = 5 V and Id = 1 ma. Recalling that Up (Miu)= 0.4 µ(n). What must W/L be for a p-channel device that provides the same performance as the n-channel device in this application?

Consider a hypothetical economy with autonomous consumption spending equal to 100 billion dollars, a marginal propensity to consume of 0.8, private investment spending of 160 billion dollars, government spending of 140 billion dollars, a balanced budget, and balanced trade (i.e. exports and imports are equal). Write a short essay comparing the effects (1) on the government budget and (2) on the equilibrium level of income in the economy of (i) a 5 billion dollar increase in government spending and of (ii) a 5 billion dollar decrease in net taxes.

Suppose the index model for stocks 1 and 2 has the following results
??1 =2%+0.8???? +??1,??2 =?1%+1.1???? +??2,???? =20%.
The standard deviations of ??1 and ??2 are 20% and 25% respectively.

(1) Calculate the standard deviation of stock 1 and stock 2.

(2) What is the covariance between each stock and the market index.

(3) What are the covariance and correlation coefficient between these two stocks?

(4) Break down the variance of each stock into its systematic and firm-specific component.

For each of the following scenarios, begin by assuming that all demand factors are set to their original values and Big Winner is charging $300 per room per night.

If average household income increases by 20%, from $50,000 to $60,000 per year, the quantity of rooms demanded at the Big Winner (falls OR rises) from (..........) rooms per night to (.........) rooms per night. Therefore, the income elasticity of demand is ( positive OR negative ) , meaning that hotel rooms at the Big Winner are ( an inferior good OR an normal good)  

If the price of an airline ticket from SFO to LAS were to increase by 10%, from $200 to $220 roundtrip, while all other demand factors remain at their initial values, the quantity of rooms demanded at the Big Winner (falls OR rises)   from (..........) rooms per night to (.........) rooms per night. Because the cross-price elasticity of demand is ( positive OR negative ) , hotel rooms at the Big Winner and airline trips between SFO and LAS are ( substitutes OR complement ).

Big Winner is debating decreasing the price of its rooms to $275 per night. Under the initial demand conditions, you can see that this would cause its total revenue to ( decrease OR increase ) Decreasing the price will always have this effect on revenue when Big Winner is operating on the ( elastic OR inelastic ).

About Hotel Legislation

1.“An innkeeper has a duty to provide goods and services in a non-discriminatory manner. An innkeeper should also be an equal opportunity employer.”

I want you to apply the concepts we have discussed in class in a fun way. I do hope you will enjoy this exercise. Once upon a time, there was an amazing group of students who lived in Cronfwoman OneFiveOne. Right next to their house, was a hotel and within that hotel was a café called Café Bastel. The amazing students were approached by an investor, Ms Finn Ance Major, who asked for their help. The investor was contemplating buying Café Bastel for $1 million and wondered if that was a good investment. What is your recommendation to Ms Finn Ance Major? Here is some information to get you started:

1. The café sells (non‐alcoholic) beverages as well as snacks and lunch

2. The café is open for 7 days, from 7am to 7pm

3. At any point in time, there are 2 employees working in the café

4. The investment horizon is 10 years 5. Use a discount rate of 12%

6. Use a tax rate of 35% You will need to make assumptions (capex, working capital…..).

There is no “right” answer – first think about the big picture (strategy, marketing, ….) and then how that story translates into your assumptions. You will be graded based on the structure of your analysis, the consistency and realism of your assumptions, your creativity, and your use of the tools/learnings from class.
