Before freezing, breaded chicken patties with the composition below are cooled to 0°c from an initial cooked temperature of 82°c (180°f). breaded chicken patty water 60% carbohydrates 15% protein 15% fat 8% ash 2%

a) what is the heat capacity (cp) of the cooked chicken (not frozen)? estimate using the choi-okos equation.

b) how much heat must be removed to cool 5 kg of breaded chicken patties?

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

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
