To determine Draw the energy grade line (EGL) and hydraulic grade line (HGL). Explanation Given: The diameter of the pipe ( d ) is 100 mm. The distance between the point A and B ( z A ) is 6m. Calculation: Consider that water in the pipe A to B as control volume. Apply Bernoulli equation between A and B . p A γ w + V A 2 2 g + z A = p B γ w + V B 2 2 g + z B Point A and point B are open to atmosphere so the pressure at point A and B are zero. p A = p B = 0 Assume velocity at point A is zero when consider the large capacity of the reservoir at A . V A = 0 Based on the above statements rewrite the equation (I) and substitute the known values in the equation to obtain the velocity at point B . 0 + 0 + 6 = 0 + V B 2 2 × 9.81 + 0 V B 2 2 × 9

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

Q2: (15 Marks) A water-LiBr vapor absorption system incorporates a heat exchanger as shown in the figure. The temperatures of the evaporator, the absorber, the condenser, and the generator are 10°C, 25°C, 40°C, and 100°C respectively. The strong liquid leaving the pump is heated to 50°C in the heat exchanger. The refrigerant flow rate through the condenser is 0.12 kg/s. Calculate (i) the heat rejected in the absorber, and (ii) the COP of the cycle.

A mass of ideal gas in a closed piston-cylinder system expands from 427 °C and 16 bar following the process law, pv1.36 = Constant (p times v to the power of 1.36 equals to a constant). For the gas, initial : final pressure ratio is 4:1 and the initial gas volume is 0.14 m³. The specific heat of the gas at constant pressure, Cp = 0.987 kJ/kg-K and the specific gas constant, R = 0.267 kJ/kg.K. Determine the change in total internal energy in the gas during the expansion. Enter your numerical answer in the answer box below in KILO JOULES (not in Joules) but do not enter the units. (There is no expected number of decimal points or significant figures).
