1) For a steady flow process, the total mass flow rate entering a control volume equals to total mass flow rate leaving. True or False 2) Mass is a conserved property. It cannot be created or destroyed during a process. It cannot cross the boundaries. True or False 3) A device has one inlet and one outlet. If the volume flow rate at inlet and outlet are the same, the flow through this device should be steady. True or False

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. Does the double hearing protection reduce the noise level…
