In this problem we will do a small analysis of flow with heat addition (Rayleigh flow) in a constant area duct. Let us refer to the inlet and exit sections of the constant areas duct as 1 and 2. Plot the exit Mach number (M2) as a function of the heat addition parameter for the following cases: a) Inlet Mach number is subsonic (M = 0.3)

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa. s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
