Q1 Determine the thermal efficiency of the basic cycle of a steam power plant (Rankine Cycle), the specific and hourly steam consumption for a 50 MW steam turbine operating at inlet conditions: pressure 90 bar and temperature 500C. The condenser pressure is 0.40 bar. Problem (1): A mechanical contractor is trying to calculate the present worth of personnel salaries over the next five years. He has four employees whose combined salaries thru the end of this year are $150,000. If he expects to give each employee a raise of 5% each year, what is the present worth of his employees' salaries at an interest rate of 12% per year? Problem (2): If a nominal interest rate of 8% is compounded continuously, determine the unknown :quantity in each of the following situations 1. What uniform end of year amount for 10 years is equivalent to $8,000 at 10 year? 2. What is the present equivalent value of $1,000 per year for 12 years? Problem (3): If you deposit $1000 per month into an account which pays interest at a rate of 12% per year compounded monthly, what is the amount of money you would have at the end of five years? Problem (4): Three different bank loan rates for electric generation equipment are listed below. Determine the effective rate on the basis of the compounding period for each rate. (1) 9% per year, compounded quarterly. (2) 9% per year, compounded monthly. Problem (5): Engineers Marci and Suzanne both invest $5000 for 10 years at 10% per year. Compute the future worth for both individuals if Marci receives annual compounding and and Suzanne receives continuous compounding
