A vertical 12-cm diameter piston-cylinder device contains an ideal gas at the ambient conditions of 1 bar and 24oC. initially the inner face of the piston is 20 cm from the base of the cylinder. now an external shaft connected to the piston exerts a force corresponding to a boundary work input of 0.1 kJ. The temperature of the gas remains constant during the process. determine
A.) the amount of heat transfer,
B.) the final pressure in the cylinder, and
C.) the distance that the piston is displayed.
The void ratio of the compacted fill is specified as 0.7. Four borrow pits are available along with each of the respective void ratios along with the cost per cubic meter for moving the soil to the proposed construction site.
An ethanol plant distills alcohol from corn. The distiller processes 2.0 t/h of feed containing 15% alcohol and 82% water; the rest is inert material. The bottoms (waste) produced is 85% of feed and contains 94% water, 3.5% alcohol, and 2.5% inert..
