4. A simple Rankine cycle uses water as the working fluid. The boiler operates at 6000 kPa and the condenser at 50 kPa. At the entrance to the turbine, the temperature is 450°C. The isentropic efficiency of the turbine is 94 percent, pressure and pump losses are negligible, and the water leaving the condenser is subcooled by 6.3°C. The boiler is sized for a mass flow rate of 20 kg/s. Determine d) the thermal efficiency.

Answer the questions below, (Insert the numerical value only, do not use ,+, *, or /) The Relative error for your answer should be less than 0.01, which means if the answer was 50, then the error should not exceed 50*0.01= ±0.5! if the answer was 230, then the error should not exceed 230*0.01= +2 3! if the answer was 2.31467*10^ 3, then you should enter this value: 0.00231467, not this 0.0023 !!!!

Q1: An item is manufactured by three machines A, B and C. Out of the total number of items manufactured during a specified period, 50% are manufactured on A, 30% on Band 20% on C. 2% of the items produced on A and 2% of items produced on B are defective, and 3% of these produced on C are defective. All the items are stored at one godown. One item is drawn at random and is found to be non-defective. What is the probability that it was manufactured on: 1-machine A? 2-machine C?
