The specific heat c of pure copper is given at 100, 200, 400, 600, and 800 k as 252, 356, 397, 417, and 433 j/kg k. employ lagrange interpolation to compute the values at 300 k and 500 k. also, compute numerical curve fitting and interpolation 301 the extrapolated value at 1000 k and compare it with the value of 451 given in the literature.

On a average work day more than work place firs are reorted

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

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.
