Control volume concept can be used to obtain forces in both internal and external flow. By drawing a control volume around a region of fluid to expose the stresses acting on the boundaries and applying the conservation of mass and conservation of momentum in integral form, the net forces acting on the fluid and hence the reaction forces acting on the solid boundary can be calculated. The advantages of this approach over differential approach are: (i) It is an easy way to obtain net forces. (ii) It gives a detailed understanding of how these forces are generated. (iii) It is commonly used in engineering practice to obtain reaction forces on pump, turbine, elbow, etc. for the design of anchoring fixtures/foundation. (A) (B) (C) (D) (i) and (ii) (i) and (iii) (ii) and (iii) All of the above

Q2: A 1.78 L four-stroke petrol engine was tested at 2500 rpm. The developed brake power is 28 kW and the brake specific fuel consumption (bsfc) is 290 g/kW.hr. Air consumption is measured by means of air-box method with orifice diameter 3.2-cm and discharge coefficient 0.62 and the pressure difference across the orifice is 150-mm-water. The ambient pressure and the temperature in the test room is 101 kPa and 20 °C. Assume: CV = 43.9 MJ/kg, PH20 =10³ kg/m³, comb = 98%, mech = 87%. (i) Determine the bmep, AFR, №v, power loss as friction, th,b. (ii) draw up the heat balance sheet on percentage basis, if the cooling water flow is 15 kg/min; rise in temperature of cooling water is 33 °C; exhaust gas temperature is 485 °C; Cpw is 4.2 kJ/kg.K and Cpexh is 1.25 kJ/kg.K.
