Asingle-cylinder four-stroke-cycle spark- ignition engine has a bsfc of 0.4 kg/kw-hr and a volumetric efficiency of 78% at a speed of 45 rps. the bore is 6 cm and the stroke is 8.5 cm. what is the fuel flow rate, fuel-air ratio, and brake torque if the brake power output is 6 kw with ambient conditions of 100 kpa and 22°c?

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
