Question 3588

A civil servant is appointed to a post through FPSC and the appointing authority wishes to grant him 8 advance increments at initial pay fixation. The post has sufficient qualified candidates available at the minimum pay scale. Under Annex-I powers for fixation of initial pay what is the CORRECT position?

Up to 6 premature increments may be granted after the FPSC's recommendation regardless of candidate availability
No premature increments should be granted because the requisite qualified persons ARE available at the minimum of the pay scale making the condition for premature increments unsatisfied✔️
The PAO has full discretion to grant any number of advance increments for FPSC-appointed staff
Up to 8 advance increments may be granted since FPSC recommended the appointment

Correct Answer Logic:

Premature increments for FPSC-appointed persons should be granted on the FPSC's recommendations AND in consideration of the fact that suitable persons of requisite qualifications are NOT available at the minimum pay of the post. Since qualified candidates are available at the minimum scale the fundamental precondition is not met and no premature increments should be granted.

Mechanical Engineering QUESTION #2434

Question 3600

The net radiation heat exchange rate between a gray surface (emissivity $\varepsilon$, area $A$, temperature $T_s$) and a large enclosure (temperature $T_{cav}$) is:

$q_{rad} = \sigma A(T_s^4 - T_{cav}^4)$ (blackbody only)
$q_{rad} = \varepsilon\sigma A(T_s^4 - T_{cav}^4)$✔️
$q_{rad} = h_r A(T_s^2 - T_{cav}^2)$
$q_{rad} = \varepsilon\sigma A(T_s - T_{cav})^4$

Correct Answer Logic:

Net radiation from a gray surface in a large enclosure: $q_{rad}=\varepsilon\sigma A(T_s^4-T_{cav}^4)$. This can be linearized as $q_{rad}=h_r A(T_s-T_{cav})$.
