How long does a car battery last?

A piston-cylinder assembly contains a two-phase liquid-vapor mixture of H20 at 220 lbf/in^2 with a quality of 75%. The mixture is heated and expands at constant pressure until a final temperature of 475°F is reached.

Specific internal energy is measured in energy per unit mass dimensions. What is 310 kJ/kg in Btu/lbm units?

One way to lower NOx emissions in diesel engines is to add water to the fuel. Since water is not mixable with diesel fuel, it has to been emulsified by a surfactant. Explain how it works and why.

What is an ip Number

An aluminum rod with a gauge length of 1.18 m undergoes thermal expansion from 20 oC to 92 oC. The thermal expansion coefficient and elastic modulus of aluminum are 22.2 * 10-6 K - 1 and 68.9 GPa respectively

Work done by a system during a process can be considered as a property of the system. a) True b) False

When the compression process is non-quasi-equilibrium, the molecules before the piston face cannot escape fast enough, forming a high-pressure region in front of the piston. It takes more work to move the piston against this high-pressure region.

hypothetical A-B alloy of composition 40 wt% B-60 wt% A at some temperature is found to consist of mass fractions of 0.66 and 0.34 for the α and β phases, respectively.
