4.6 Determine the quality of a two-phase liquid-vapor mixture of: Refrigerant 134a at -40\deg F with a specific volume of 5.7173 ft^3/lb. (I prefer the process write with a computer than handwriting)

Question 1: A steady, two-dimensional, incompressible velocity field has cartesian velocity components u = Cy(x² + y²) and v=-Cx(x² + y²), where C is a constant. Transform these cartesian velocity components into cylindrical velocity components u, and ua, simplifying as much as possible. You should recognize this flow. What kind of flow is this? Is this flow follow the continuity equation?

Given what you know about thermodynamics, the energy balance equations that you have learned, etc. Prove that for an adiabatic, reversible pump,          -Ws/m = V∆P. Show your work and state assumptions.

Above and to the right of the critical point is a phase called the supercritical fluid, which is where separate phases do not coexist. Select one: O True False

Just B. please

The figure is shown in the question in the second picture

Fluid Mechanics easy question

1) Pavithran Ravindran explains to a group of inspiring CBE students that the Reynolds number is a dimensionless group defined for a fluid flowing in a pipe as Re = Dvp/µ where D = pipe diameter, v = average fluid velocity, p = fluid density, and u = fluid viscosity. When the value of the Reynolds number is less than about 2100, the flow is laminar -- the fluid flows in smooth streamlines. For Reynolds numbers above 2100, flow is turbulent -- a great deal of internal agitation takes place. %3D Methyl ethyl ketone (MEK) flows through a 2.067-in. ID pipe at 20°C, at which temperature its density is 0.805 g/cm³ and its viscosity is 0.43 centipoise (1 centipoise = 1.00 x 10-3 kg/m.s). The average fluid velocity is 0.048 ft/s. Determine whether the flow is laminar or turbulent. %3D

Consider the steady, isothermal, irrotational flow of an incompressible frictionless fluid subject only to a body force characterized by a potential O, where F,=- V@ (in units of force/volume). Since the fluid is frictionless, the only surface force is due to pressure, F =-pn. By completing a momentum balance on a material volume of fluid subject to the constraints listed above, derive Bernouilli's law, P + ½pv² + O = constant along a fluid streamline.
