For an ideal gas undergoing a fully irreversible isothermal expansion where ΔE = 0 and ΔH = 0, what are the values of ΔQ and ΔS_______________?
Show answer Hide answer
Answer: B. ΔQ = 0, ΔS = +ve
Explanation
For an isothermal irreversible expansion of an ideal gas, internal energy and enthalpy changes are zero, but entropy increases due to irreversibility while heat transfer is non-zero.

Q1. For a centrifugal pump, the ratio h1/h2 is designated as the _____________ efficiency (where h1 = measured actual head, h2 = head imparted by the impeller)?
Show answer Hide answer
Answer: A. Mechanical
Mechanical efficiency evaluates internal frictional losses in bearings, seals, and stuffing boxes. It is defined as the ratio of actual delivered pump head to the theoretical head imparted by the impeller. This efficienc...
Q2. For condensers and evaporators running under identical terminal parameters, the logarithmic mean temperature difference (LMTD) for counter-flow compared to parallel flow is__________________?
Show answer Hide answer
Answer: C. Equal
Logarithmic mean temperature difference calculates average thermal driving force in heat exchangers. In single-phase condensers and evaporators, one fluid undergoes phase change at constant temperature. Mathematical deri...
Q3. When water (Prandtl number roughly 6) flows over a flat plate heated across its entire span, how does thermal boundary layer thickness compare to hydrodynamic boundary layer thickness?
Show answer Hide answer
Answer: A. Less
The Prandtl number represents the ratio of momentum diffusivity to thermal diffusivity in fluids. For water, the Prandtl number is approximately six, meaning momentum diffuses faster than heat. Consequently, the hydrodyn...
Q4. In brass alloys, reducing zinc content while increasing copper content results in an elevation of its _____________?
Show answer Hide answer
Answer: A. Percentage elongation
Reducing zinc and increasing copper content in brass alloys enhances material ductility. Higher copper fractions allow planes of atoms to slide past each other easily. This microstructural change directly results in an e...
