Assume the gasoline is burned with 99% efficiency in a car engine, with 1% remaining unburned in the exhaust gases as vocs (volatile organic compounds). if the engine exhausts 16 kg of gases (mw=30) for each kg of gasoline (mw=100), calculate the fraction of vocs in the exhaust. give your answer in parts per million

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

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.
