Over the open ocean, if the air-sea temperature difference is zero, then which of the following statements is/are always true?
Show Hint
- Sensible heat flux is zero.
- Latent heat flux is zero.
- Momentum flux is zero.
- Net energy flux is zero.
The Correct Option is A
Solution and Explanation
Step 1: Sensible Heat Flux
Sensible heat flux is the transfer of heat due to temperature differences. Since the temperature difference between the air and sea is zero, the sensible heat flux will be zero.
Step 2: Latent Heat Flux
Latent heat flux depends on the difference in moisture content between the air and the sea, and it is not necessarily zero when the temperature difference is zero. Therefore, latent heat flux is not always zero in this condition.
Step 3: Momentum Flux
Momentum flux depends on wind speed and does not necessarily become zero when the temperature difference is zero. Therefore, momentum flux is not always zero.
Step 4: Net Energy Flux
Net energy flux refers to the total energy transfer, including both heat and work, and it is not necessarily zero when the temperature difference is zero.
Final Answer: \[ \boxed{\text{(A) Sensible heat flux is zero.}} \]

Two Carnot heat engines (E1 and E2) are operating in series as shown in the figure. Engine E1 receives heat from a reservoir at \(T_H = 1600 \, {K}\) and does work \(W_1\). Engine E2 receives heat from an intermediate reservoir at \(T\), does work \(W_2\), and rejects heat to a reservoir at \(T_L = 400 \, {K}\). Both the engines have identical thermal efficiencies. The temperature \(T\) (in K) of the intermediate reservoir is ........ (answer in integer).

A bar of length \( L = 1 \, {m} \) is fixed at one end. Before heating its free end has a gap of \( \delta = 0.1 \, {mm} \) from a rigid wall as shown in the figure. Now the bar is heated resulting in a uniform temperature rise of \( 10^\circ {C} \). The coefficient of linear thermal expansion of the material is \( 20 \times 10^{-6} / \degree C \) and the Young’s modulus of elasticity is 100 GPa. Assume that the material properties do not change with temperature.
The magnitude of the resulting axial stress on the bar is .......... MPa (in integer).
