Explanation Given Information: The temperature of brine solution is − 29 ° C , initial temperature is 1 ° C , the freezing temperature of turkey is − 2.8 ° C , final temperature − 18 ° C , specific heat above freezing point is 2.98 kJ / kg ⋅ ° C , specific heat below freezing point is 1.65 kJ / kg ⋅ ° C , mass of turkey is 7 kg and latent heat of fusion is 214 kJ / kg . Write the Expression of amount of heat required to achieve freezing point. Q 1 = m c p ( T i − T f ) Here, mass of turkeyis m , specific heat of turkey above freezing point is c p freezing temperature is T f and initial temperature is T i . Write the Expression of latent heat of fusion. Q 2 = m L Here, latent heat is L . Write the Expression of amount of heat require achieving Final temperature. Q 3 = m c p' ( T f − T 0 ) Here, mass of turkey is m , specific heat of turkey below freezing point is c p' freezing, final temperature to be achieved is T 0 . Write the Expression of total heat transfer rate. Q T = Q 1 + Q 2 + Q 3 Substitute m c p ( T i − T f ) for Q 1 , m L for Q 2 and m c p' ( T f − T 0 ) for Q 3 To determine (b) The amount of heat transfer when 90 % water content.

A piston-cylinder device initially contains 0.08 m^3 of nitrogen gas at 130 kPa and 170°C. The nitrogen is expanded to a pressure of 80 kPa via isentropic expansion. Determine the final temperature and the boundary work done by the system during this process.

A Carnot (ideal) heat pump is to be used to heat a house and maintain it at 22°C in winter. On a day when the average outdoor temperature remains at about 0°C, the house is estimated to lose heat at a rate of 65,000 kJ/h. If the heat pump consumes 6 kW of power while operating, determine: (a) how long the heat pump ran on that day (b) the total heating costs, assuming an average price of 11¢/kWh for electricity (c) the heating cost for the same day if an 85% efficient electric furnace is used instead of a heat pump.

From the information in the image, I needed to find the orientation of U relative to Q in vector basis q_hat. I transformed the euler angle/axis representation to euler parameters. Then I got its conjugate in order to get the euler parameter in N frame relative to Q. The problem gave the euler angle/axis representation in Q frame relative to N, so I needed to find the conjugate. Then I used the euler parameter rule of successive rotation to find the final euler parameters that describe the orientation of U relative to Q. However that orientation is in n_hat which is the intermediate frame. How do I get the final result in q_hat?
