A family wants to replace their 25 year old gas-fired combi boiler (24 kW) where the unit cost of natural gas is ₺0.15/kWh. The current combi has 60% efficiency and operated for 2 hours a day for 3 months each year. The family wants to make a decision whether to buy a new combi with 90% efficiency and ₺4000 cost. Give your suggestion to this family whether to buy the new one or keep the current one considering a simple payback period of 5 years.

Yeji just came back from dance practice and went straight to her bedroom. It was summer so the temperature in her bedroom was estimated to be around 40°C. She then turned her air conditioner on, closed her door and windows, and it cooled her bedroom to 18°C in 20 minutes. Calculate,a. How much heat was transferred to cool her bedroom to 18°C?b. What is the power consumption of the air conditioner, in kW?The air conditioner has a COP of 2.8. Assume the mass of her entire bedroom to be 750 kg of air, Cv = 0.72 kJ/kg.°C and Cp = 1.0 kJ/kg.°C.*Round off all answers to four decimal places*

1. In a turbine, steam enters with an enthalpy of 1275 Btu/lbm and leaves with an enthalpy of 1115 Btu/lbm. The transferred heat is 13 Btu/lbm. Find the turbine work in hp where the steam flow rate is 5 lbm/sec? 2. During a steady flow process, the pressure of the working substance drops from 200 to 20 psig, the speed increases from 100 to 800 fps, The internal energy of the open system increases by 15 Btu/lbm, and the specific volume increases from 1 to 10 ft3/lb. The heat lost of the open system is equivalent to 1 kW. Determine the work in hp for a mass flow rate of 12 lbm per min.
