A14 kw cooling load is to be served by operating an ideal vapor-compression refrigeration cycle with its evaporator at 320 kpa and its condenser at 800 kpa.

calculate the refrigerant mass flow rate and the compressor power requirement when refrigerant-134a is used.

(take the required values from the saturated refrigerant-134a tables.)the refrigerant mass flow rate is kg/s. the compressor power requirement is kw.

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges

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
