Aphase separator receives 2.5 kg/s of r134a at 0 c with a quality of 60%. saturated liquid exits through the separator bottom at a rate of 1.5 kg/s. saturated vapor exits through the separator top at a rate of 0.25 kg/s. the phase separator is initially filled entirely with 0 c saturated liquid. a) what heat transfer is required to get mixture within the phase separator to 50% quality? report your answer in kj. b) what mass of r134a enters the separator? report your answer in kg.

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k

Prove the equivalence between the two statements of the 2nd law of thermodynamics (i.e., a violation of one statement leads to the violatio the other statement)

For a process taking place in a closed system containing gas, the volume and pressure relationship is pvi-constant. -1.5 bar, the process starts with initial conditions, pi = =0.03 m3 and ends with final volume, v2-0.05 m3 determine the work done by the gas.
