A convenient and cost-effective way to store biogas is to use light-weight, rigid gas containers. The pressure and temperature of biogas stored in a 10 m^3 container are 1.5 bar and 5°C, respectively, as measured at an early morning time (state 1).

Consider the combustion of ethanol C2H5OH with air. Assume the air is dry and comprised of 21% oxygen and 79% nitrogen on a molar basis. a. Determine the air/fuel ratio on a molar basis. b. Determine the air/fuel ratio on a mass basis.

A 25-kg cast-iron wood-burning stove contains 5kg of soft pine wood and 1 kg of air. All the masses are at room temperature, 20 degree C, and pressure, 101 kPa. The wood now burns and heats all the mass uniformly, releasing 1500W.
