- A boiler plant raises 5.2 kg/s of steam at 1825 kN/m² pressure, using coal of calorific value 27.2 MJ/kg. If the boiler efficiency is 75%, how much coal is consumed per day? If the steam is used to generate electricity, what is the power generation in kilowatts assuming a 20% conversion efficiency of the turbines and generators?Let's assume that we generate electrical energy by means of a turbine generator. Before the steam enters a reversible adiabatic turbine, it must be raised to 10000 kPa pressure and 450 ºC. As the steam leaves the turbine, its pressure drops to 150 kPa and a temperature of 100 C. The flow of steam in the turbine is 57 kg / s. In the meantime, your ambient temperature was measured as 25 ºC and pressure as 100 kPa. Considering these conditions, how much exergy does the steam have when entering and leaving the turbine? How much power does the turbine generate? How much power can be produced from this turbine and what is the second-law efficiency of this turbine? Calculate.A solar collector absorbed 40W/m^2 heat from the atmosphere. This is equal to the convection brought by air for drying pupose. If the temperature of the air is 40 degrees Celsius while the solar collector area's temperature is 80 degrees Celcius and neglecting effect of radiation, find the convective heat transfer coefficient.
