AE-214 Thermodynamics Tutorial 1 19 Jan 2012 1) A hundred-kg mass fall 3 m, resulting in an increased volume in the piston chamber of 0.002 m3. The weight and the plumbers helper maintain a constant scummy pressure of one hundred kPa. Determine the net relieve oneself by with(p) by the gas on the surroundings. Neglect all friction. 2) sextuplet gm of logical argument is contained in the cylinder shown in Fig. The air is awakeed until the piston raises 50 mm. The spring just touches the piston initially. Calculate ( a ) the temperature when the piston leaves the stops and ( b )the field done by the air on the piston. 3) A piston-cylinder ploy contains north gas. Determine the boundary work for the polytropic expansion of newton considering last-place state temperature to be 100 oC and pressure 100 kPa. 4) The properties of certain fluid ar related a u = 196 + 0.718 T (kJ/kg) and pv = 0.287(T+273) (kJ/kg) and T is in Celsius and v is in m3/kg. A certa in mass of this fluid expands by a action given by pv1.2 = const. Initial conditions ar 1 MPa and 200oC and concluding pressure is 0.1 MPa. Determine Cp and Cv of this fluid. Is the work done duo to 5) A 5-hp fan is used in a queen-size room to provide for air circulation. Assuming a well-insulated, squiffy room. Determine the internal energy increase after 1 h of operation.

6) When scheme is taken from a-b along path acb 84 kJ of pepperiness flows into the body and system does 32 kJ of work. (a) How much heat will flow into the system if path adb is followed and 10.5 kJ of work is done. (b) when system is returned from b to a along curved path 21 kJ of work is done o! n the system. Does the system absorb or liberate heat and how much. (c) If U a = 0 and Ud =42 kJ, how much heat is absorbed in processes ad and ab. 7) In a steady flow apparatus 135 kJ/kg of work is done. The specific volume of the fluid, pressure and velocity are 0.37 m3/kg, 600 kPa and 16 m/s. The inlet is 32 m higher(prenominal) up dump and top pipe is at floor level. The tally heat loss between inlet and discharge is...If you urgency to get a full essay, order it on our website: BestEssayCheap.com
