In the figure, it shows that,

OA → Sensible heating

OB → Sensible cooling

OC → Humidification

OD → Dehumidification

OE → Heating + humidification

OF → Cooling + dehumidification

OG → Cooling + humidification

OH → Heating + dehumidification

In heat exchangers, the humid air is cooled, and (partial condensation) dehumidification is taking place. So the OF will be the process which is diagonal to the left side in a downward direction.

Statement (I): Piston temperature profiles near full load are flattened in case of liquid cooled engines whereas for air cooled engines temperature profiles are steeper. Statement (II): The piston temperature profiles are different in nature for liquid cooled and air cooled engines because of the different values of heat capacities.
On a P-V diagram of an ideal gas, suppose a reversible adiabatic line intersects a reversible isothermal line at point A. Then at a point A, the slope of the reversible adiabatic line $${\left( {\frac{{\partial {\text{P}}}}{{\partial {\text{V}}}}} \right)_{\text{S}}}$$  and the slope of the reversible isothermal line $${\left( {\frac{{\partial {\text{P}}}}{{\partial {\text{V}}}}} \right)_{\text{T}}}$$  are related as (where, $${\text{y}} = \frac{{{{\text{C}}_{\text{p}}}}}{{{{\text{C}}_{\text{v}}}}}$$  )
