What size unit is neededfor a house with a heat load of 28,576 Btu/h? (Round up to the next highereither half or whole number.)Hello Sir,Good Morning.I have a question in my homework related thermodynamics lesson. The following below is my question. Please advice. Thank you. Regards,Irfan An air conditioning system is used to keep the house at 65°F when the outside temperature is 85°F. The house gets heat through the walls and windows at a rate of 810 Btu/min, and the rate of heat generation inside the house from occupants, lights, and equipment is 120 Btu/min. Determine the minimum power input required for this air conditioning system.
- 2. Conduction is function of the environment's humidity and the airflow/exchange next to the skin. True False 3. One of the amendments to Regulation 854 that came into force in 2016 is strengthening and improving requirements regarding high visibility safety apparel. True False 4. Cold stress is also known as "thermal strain". True False 5. Dynamic force presents a greater risk of strain than static force. True False 6. In underground climate, auto compression of air adds 4-60C/km to the wet bulb temperature. True False An industrial machinery gives out 112 dBA of noise 1 m away from the source, which requires double hearing protection. You are a worker performing work for 8-hrs around the machinery and you are required to wear double hearing protection. An earplug which has an NRR of 29 dB and an earmuff with an NRR of 31 dB. The suggested derrating percentage of the hearing protections are 60% and 55% of the NRR, respectively.
