In ansys they have two options incompressible ideal gas (density only vary with temperture) and ideal gas? . can someone write me the navier-stokes equations for both cases when the ideal gas is incompressible and when it is incompressible for natural convection flow.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
