Thermodynamics 1 True/ False questions

Thermodynamics theory questions

For every control volume at steady state, the total of the entering rates of mass flow equals the total of the exiting rates of mass flow

If a closed system undergoes a process for which the work is negative, and the heat transfer is positive, the total energy of the system must increase.

For one-dimensional flow, mass flow rate is the product of density, area and velocity

For a control volume, flow rates are conserved due to the conservation of mass.

Approximate values for V, U, and H at liquid states can be obtained using saturated liquid data because the values of v and u for liquids change very little with temperature at a fixed pressure.
