Question

Note: Sketch a simple schematic
diagram with clearly indicated control volume, its control surface and all the data displayed on it

no need to finding the required data i already solved it just Sketch a simple schematic
diagram with clearly indicated control volume, its control surface and all the data displayed on it

An 8-cylinder (k = 8), 4-stroke cycle, petrol engine with a compression ratio of 11
must be designed to produce 70 kW of brake power (W, ) with a torque (7.) of 200
N•m. At these conditions, all kind of mechanical losses are 22%, and the brake mean
effective pressure (Pom) is 555 kN/m². For the air-standard cycle, P1 = 101.325 kN/m²,
T1 = 310 K, and y= 1.4. The indicated fuel flow rate (i.e., sfcina) 0.401 kg/(kW•h),
where the power is indicated power(W/na) and the fuel has a lower heating value
(LHV) of 44000 kJ/kg. The ratio of the piston bore (D) to stroke (L) is 1.20. Deter-
mine:
(a) The bore (D) and stroke (L), both in cm. D=9.5 cm & L =7.96cm
(b) The indicated thermal efficiency (7h.ind) - thermal efficiency =0.204
(c) The brake engine efficiency(n,). brake engine efficiency = 0.16
