Need help to answer. ASAP. Air at a temperature of 150C passes through a heat exchanger at a velocity of 30 m/s where its temperature is raised to 8000C. It then enters a turbine with the same velocity of 30 m/s and expands until the temperature falls to 6500C. On leaving the turbine, the air is taken at a velocity of 60 m/s to a nozzle where it expands until the temperature falls to 5000C. If the air flow rate is 2 kg/s, calculate the following. (i) Rate of heat transfer to the air in the heat exchanger, (ii) Power output from the turbine assuming no heat loss, and (iii) Velocity at exit from the nozzle, assuming no heat loss. Take the enthalpy of air as h =cpt, where cp is the specific heat equal to 1. 005kJ/kg K and t is the temperature.

PS.52 The Station, a boutique cookie company, needs to create a production process for its new cinnamon malt ball cookies. To help accomplish this, the company has put together some numbers for production costs (per dozen cookies for the variable costs). Pre-Bake$150 Fixed Costs $1.75 Labor Costs $0.59 Material Costs Easy Bake$350 Fixed Costs $1.53 Labor Costs $0.48 Material Costs Speed Bake$550 Fixed Costs $1.35 Labor Costs $0.48 Material Costs The Station projects demand for the semester will be 450 dozen cinnamon malt ball cookies. Due to the cookies' expected popularity the selling price will be $4.49.A. Based on the projected demand (volume) for the semester, which process type should they select?1. Pre-Bake2. Easy Bake3. Speed BakeB. Under this process typethe one selected in the previous questionwhat would be their profits for the semester? (Display your answer to one decimal place.)C. If demand were to increase, what would be the break-even point (in unit volume or demand) between the selected process and the next process option? (Display your answer to two decimal places.)D. Beyond this break-even point, which process would be best?1. Pre-Bake2. Easy Bake3. Speed BakeE. Based on the break-even point (derived two questions back), what would be the total cost? (Display your answer to two decimal places.)
