A turbine operating under steady flow conditions receives steam at the
following state : pressure 13.8 bar ; specific volume 0.143 m3/kg ;
internal energy 2590 kJ/kg ; velocity 30 m/s. The state of the steam
leaving the turbine is : pressure 0.35 bar ; specific volume 4.37 m3/kg
; internal energy 2360
kJ/kg ; velocity 90 m/s. Heat is lost to the surroundings at the rate of
0.25 kJ/s. If the rate of steam flow is 0.38 kg/s, what is the power
developed by the turbine ?
Write a function that takes an input parameter as a String. The function should replace the alternate words in it with “xyz” and print it. Words are separated by dots. (Avoid using inbuilt function) If input is “i.like.this.program.very.much” Output will be “i.xyz.this.xyz.very.xyz” in java
Consider a firm that uses capital and labor as inputs and sells 5,000 units of output per year at the going market price of $10. Also assume that total labor costs to the firm are $45,000 annually. Assume further that the total capital stock of the firm is currently worth $100,000, that the return available to investors with comparable risks is 10 percent annually, and that there is no depreciation. Is this a profitable firm? Explain your answer.
Suppose a consumer having a disposable income of 300 birr consumers only two commodities X and Y and his utility function is given as U(X,Y)=50X-X2+25Y given further that price of X and Y are 1 birr and 2.5 birrr respectively, determine:
A. The consumer's optimal bundles
B. His Marginal utility of income and its interpretation

The production function of a firm is given by Q=4L1/2K1/2 suppose the cost of labor is birr 40 per unit and the cost of using capital is Birr 10 per unit
A. Determine the amount of labor and capital that should be used in order to minimize the cost to produce 40 units of output?
B. Calculate the minimum cost of producing 40 units?
