Q1. SECTION-A Prove that in case of forced vortex, the rise of liquid level at the ends is equal to the fall of liquid level at the axis of rotation. Explain, with the aid of neat sketch, the working principle of a Pitot static tube. Further, explain how the Pitot static tube differs from the Pitot tube. Using an ideal gas as working fluid, show that the thermal efficiency of an Ericsson cycle is identical to the efficiency of a Carnot cycle operating between the same temperature limits. Distinguish between the following : Explain the effects of the following variables on the volumetric efficiency of an IC engine :
(i) Thermodynamics and Heat transfer
(ii) Free convection and Forced convection
(iii) Black body and Gray body
(i) Types of fuel
(ii) Valve overlap
(iii) Inlet valve timing
(iv) Exhaust residual
(v) Exhaust gas recirculation
(vi) Engine speed
