A ribbed cylinder of outside diameter 0.6m is at a surface temperature of 260℃ in large surroundings at 20℃. Calculate the heat transfer coefficient for radiation, and the total heat loss rate due to radiation and convection. The cylinder is 0.9m long and is made of cast iron of emissivity 0.8. The surface area of the ribbed cylinder is 5 m2. and the heat transfer coefficient for convection may be taken as 8.8 W/m2K. Neglect end effects.

The current price of a non-dividend paying stock is $90. Use a two-step binomial tree to value a European call option on the stock with a strike price of $88 that expires in 6 months. Each step is 3 months, the risk free rate is 5% per annum with continuous compounding. What is the option price when u = 1.2 and d = 0.8? Assume that the option is written on 100 shares of stock.

5 (1) Calculate, stepwise, the weights of KH2PO4 and K2HPO4 . You need to prepare 1000 mL of 0.8 M phopsphate buffer, ph 7.5 (Two decimal place in all the calculation steps please).
(2) Calculate the K+ concentration of the phosphate buffer. And convert the final unit to mM
(3) if the pH of th phosphate buffer you made did not equal 7.5, can you explain why?

Engineers want to design seats in commercial aircraft so that they are wide enough to fit 99% of all males. (Accommodating 100% of males would require very wide seats that would be much too expensive.) Men have hip breadths that are normally distributed with a mean of 14.3 in. and a standard deviation of 0.8 in. Find Upper P99. That is, find the hip breadth for men that separates the smallest 99% from the largest 1%.

Crisp Cookware's common stock is expected to pay a dividend of $2 a share at the end of this year (D1 $2.00); its beta is 0.8. The risk-free rate is 5.3% and the market risk premium is 6%. The dividend is expected to grow at some constant rate, gL, and the stock currently sells for $50 a share. Assuming the market is in equilibrium, what does the market believe will be the stock's price at the end of 3 years?

A load draws 3500 W of power at a lagging PF of 0.6 from 500-Vrms, 120 Hz sinusoidal source. a. (8) Calculate the complex power consumed by the load. b. (10) Calculate the capacitance needed to correct the power factor to 0.8 lagging. c. (7) Draw the power triangles to reflect power system before and after the PF correction. Label all sides and power angles numerically.

An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 190 engines and the mean pressure was 6.0 pounds/square inch (psi). Assume the population standard deviation is 0.8. If the valve was designed to produce a mean pressure of 6.1 psi, is there sufficient evidence at the 0.02 level that the valve does not perform to the specifications?

2. The magnitude of price elasticity of demand
directly affects the change in income resulting from the change in
prices by the producer. Let's say that the price elasticity of
professional baseball tickets is 0.8 if the ticket price is between
3,000 and 5,000 , and 1.2 if the ticket price is between 5,000 and
7,000 , and 2 if it is over 7,000 .
Currently, the admission fee is 5,000. How should the admission fee

Consider a multiplicative binomial model with N = 3, r = 0, u = 1.2, d = 0.8 and S 0 = 100. At time t = 1 when S 1 = 120 a (european) call option with maturity at T = 3 and struck at 100 is quoted at 25. Is that a fair value? If yes explain why? If not explain why and explicitly define an arbitrage strategy (you have to give details of the arbitrage strategy)
