Methane (ch4) at 25°c ,1 atm is combusted with 75% excess air at 25°c, 1 atm with a volumetric flow rate of 1.5 m^3/s in an adiabatic process with an ambient temperature of to=25°c and pressure of po=1atm (a)-write the balanced reaction equation for the process (b)-determine the air to fuel ratio (c)-determine the temperature of the products (d)-determine the rate of entropy generation (e)-determine the rate of exergy destruction

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
