Question

Mechanical Engineering

Q4. State whether the following are true orfalse with a brief explanation (1-2 sentences).

(i) Given a control volume with one inlet and two exits, the twoexits must have identical mass flow rates.

(ii) You are given a control volume with one inlet and one exitsuch that more ‘mechanical energy’ is coming in than going out(‘mechanical energy’ is the sum of enthalpy, kinetic energy andpotential energy per unit mass), but are given no information onthe work or heat interactions. The total energy (Ecv) within thecontrol volume must increase with time.

(iii) You are given a control volume where the mass is changingwith time but the control volume itself has no heat or workinteractions with the surroundings. The total energy within thiscontrol volume must also change with time.

(iv) For a one-inlet, one-exit control volume at steady state,the volumetric flow rates must be equal at the inlet and theexit.

(v) An open control volume (i.e., with inlets and exits), bydefinition, always describes the same region and therefore, thespecific volume of matter inside cannot change.
