ASSIGNMENT: Coursework on Fluid Mechanics and Thermal Dynamics

(a). Give the definitions to the concepts used in thermodynamics and fluid mechanics:  Process  Cycle  Real gas  Perfect gas  1 st law of thermal dynamics  Thermal equilibrium  Viscosity  Inviscid fluid  Control volume  Steady flow

(b) Answer all following questions (1). If you put cold water into a blender and mix it rapidly for several minutes, the water will become warm. Where does the additional thermal energy come from? [4 marks] (2) State the conditions that should be met to apply Bernoulli’s equation. [7 marks] (3) State the conditions which must be applied if a thermodynamic operation is to be reversible.

Question 2 (25 marks) (a) For the manometer shown in the figure below, calculate the pressure difference pA-pB. The water density water is taken as 1000 kg/m3 . The specific gravities for mercury and oil are 13.6 and 0.86 respectively.

(b) A bucket is filled from a garden water butt as shown in Fig Q2 (b). The butt is filled with water to a level of hfill = 1.5 m. The water is discharged via a 10 mm round pipe (Dpipe) near the bottom of the tank.

Question 3 (25 marks) A Venture meter shown in Fig. Q3 is essentially a convergent-divergent construction in a pipeline. The change in pressure in the liquid as it passes through the meter can be used to determine the flow rate.
