A fuel gas consists of 75% butane (C4H10), 10% propane (C3H8) and 15% butene (C4H8) by volume. It is to be fed to the combustion chamber in 10% excess air at 25ºC, where it is completely burnt to carbon dioxide and water. The flue gases produced are to be used to generate 5 bar steam from water at 90ºC. net calorific value (MJm-3) at 25oC Butane (C4H10) = 111.7MJm-3, Butene (C4H8) = 105.2 MJm-3. Propane (C3H8) = 85.8 MJm-3. air...

please show work for all sub parts
A combined cycle gas turbine / vapor power plant uses the turbine exhaust as the energy source for the boiler. Each power system uses a single turbine. The gas power system is modeled as an ideal air-standard Brayton cycle. The vapor power system is modeled as an ideal Rankine cycle. Given specific operating conditions determine the temperature and pressure at each state, the rate of heat transfer in the boiler, the power output...

Please answer question 6. thanks
1. A 7 kg lead sphere that has 35 °C temperature falls through the air. When the sphere is 15 m above the ground, its speed is 20 m/s. Suppose that when the sphere hits the ground, 75% of its kinetic energy converts to heat that raises its temperature. Specific heat capacity of lead c = 128 J/kg.°C, g=9.8 m/s. A. Setup with a labeled diagram. b. Write down in symbols the energy equation. c....
