جية - A - Northern Technical University Technical Eng. College/Kirkuk Fuel and Energy Eng. Tech. Dep. 4th Year Students Final Examination (2022-2023) Subj.: Process of unit operation Date: 6/6/2023 Time: 3 Hours: Morning & Evening Study Note/Answer only four questions, including the first question Q.1: Water is to be cooled in a packed tower from 330 to 295 K by means of air flowing counter currently. The liquid flows at the rate of 275 cm³/m² s and the air at 0.7 m³/m² s. The entering air has a temperature of 295 K and a humidity of 20%. Calculate the required height of tower and the condition of the air leaving at the top. The whole of the resistance to heat and mass transfer can be considered as being within the gas phase and the product of the mass transfer coefficient and the transfer surface per unit volume of column (ha) may be taken as 0.2 s¹. Assuming, the latent heat of water at 273 K = 2495 kJ/kg, specific heat capacity of dry air = 1.003 kJ/kg K, specific heat capacity of…

PLEASE HELP ME ANSWER THIS PROBLEM
Please explain all parts and which formulas to use
In company that designs road cars and heavy trucks, it important to make the proper selection of the engines. Your part as a system energy engineer is to make a proper selection between an engine operates on Otto cycle/gasoline engine or Diesel cycle/diesel engine. Your head of department asked you to provide a detailed technical report that shows your selection for engine to be used with heavy truck vehicle. This is best achieved by performing the following tasks: Section.1: 1. Which engine does operate at lower rpm and has higher air-fuel mass ratio? 2. Which engine does burn fuel more completely? 3. Which engine has lower fuel cost? 4. Explain what compression ratio for Otto and Diesel cycles means 5. Explain what cut-off ratio for Diesel cycles means 1:06 pm 6. Explain the limitations of SI engines in terms of their ability to operate at much higher compression ratios. What is this limitation called? 7. Provide general plot(s) for thermal efficiency, 7 vs compression ratio, r for…
Pls. Answer thank you! An auditorium seating 1600 people is to be maintained at 80°F dry bulb and 65°F wet bulb temperature when outdoor air is at 91oF dry bulb and 75oF wet bulb. Solar heat load is 120,000 Btu/hr and supply air is at 60°F, determine the amount of supply air. (Use sensible heat load of 225 Btu/hr per person)
Pls. Answer thank you! An air-conditioning system is used to maintain a house at 75°F when the temperature outside is 95°F. The house is gaining the heat through the walls and windows at a rate of 1250 Btu/min, and the heat generation rate within the house from people, lights, and appliances amounts to 350 Btu/min. Determine the minimum power input required for this air-conditioning system.
Create a Refrigeration Cycle Steps: You can start at an point in the cycle in the picture, but you must follow this order and you must make it through the entire cycle. The following must be included also and explained /defined Evaporation, Condensation, Fan for the Condenser and Blower for the evaporator. Provide good information
Pls.answer thank you! A classroom that normally contains 40 people is to be air-conditioned with window air-conditioning units of 5 KW cooling capacity. A person at rest may be assumed to dissipate heat at a rate of about 360 KJ/hr. There are 10 light bulbs in the room, each with a rating of 100 watts. The rate of heat transfer to the classroom through the walls and the windows is estimated to be 15,000 KJ/hr. If the room air is to be maintained at a constant temperature of 21°C, determine the number of window air-conditioning units required.
Topic: HEAT ENGINES, HEAT PUMPS & THERMAL EFFICIENCY The energy transferred by heat from an engine during one cycle is 500 J. Howmuch energy must be added to the engine so that it can operate at 30%efficiency?
Q4: Describe the suitable major plumbing and firefighting systems for a small residential villa building ?
select if true or false for the following questions 1. For a standard condenser in a refrigeration system, the thermal energy (in J) is equal to the mass (in kg) multiplied by the change in enthalpy across the condenser (in J/kg). 2. Consider a basic refrigeration cycle: Since it requires less work to compress a liquid than a vapor, the entire refrigeration process would work better if the compressor was replaced with a pump. All else being equal, increasing the mass-flow rate of refrigerant will increase the rate of heat transfer at the system’s evaporator. All of these (except, of course, the one labeled, “None of these.”) None of these.
