a. Steady flow and unsteady flow b. Compressible and incompressible c. Laminar flow and turbulent flow.

What is the best description of the difference between compressible flow and incompressible flow?Group of answer choicesIn compressible flow, the flow is always turbulent, while in incompressible flow, the flow is always laminarIn compressible flow, for a straight pipe the rate of pressure drop is a function of the pipe position, whereas it decreases continuously for incompressible flowCompressible flow deals with fluids that have variable temperature, while incompressible flow deals with fluids that have constant temperatureIt is never appropriate to use the incompressible flow assumption for gases for any gas flow system

Differentiate between lamina and turbulent flow.

Since liquid can be considered as incompressible, the volume flow rates into and out of a steady flow device will remain constantGroup of answer choicesTrueFalse

A flow is said to be one-, two-, or three-dimensional _____.Group of answer choicesdepending on whether the flow is laminar, transitional, or turbulentif the flow velocity varies in one, two, or three primary dimensions, respectively.if there are no changes in properties, velocity, temperature, etc., at a point with timedepending on the level of variation of density during flow

During the isentropic expansion of a flow in an ideal choked diverging nozzle:Group of answer choicesThe static pressure is decreasing as the velocity and Mach number decreasesThe static pressure remains constantThe total enthalpy and the static pressure are dropping as the Mach number increasesThe static pressure is decreasing as the velocity and Mach number increases
