Pls show detailed handwritten solution 

4. An electric blender is used to grind soaked soya beans with initial internal energy of 3000 joules. If the power consumption is 0.1 KW, with heat loss from the blender is 20 joules/sec., determine the time in minutes the operation of the blender to make the final internal energy of 27,000 joules. 5. The enthalpy of air is increased by 139.586 KJ/kg in a compressor. The rate of air flow is 16.42 kg/min. The power input is 48.2 KW. Determine the heat flow in KW.
