Find the engine volume and compression ratio from the paper. Use those numbers to calculate the following and list any assumptions you make about the cycle in your document. Assume that air has γ-1.4 and R-287 J/kgK. and the engine is running an air-standard ideal Otto cycle. a) Indicated work produced each cycle (in Joules)
b) Heat addition each cycle (in Joules) - assume the engine runs off gasoline with a lower heating value of 42 MJ/kg and air-to-fuel ratio of 14.7 (stoichiometric for gasoline). The lower heating value is the amount of heat generated from the combustion of a liquid fuel per unit mass.
c) Indicated thermal efficiency of the engine.

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false

Derive the correction factor formula for conical nozzle i=-(1+ cosa) and calculate the nozzle angle correction factor for a nozzle whose divergence hal-fangle is 13 (hint: assume that all the mass flow originates at the apex of the cone.

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
