2- Saturated liquid Refrigerant 134a enters the valve at a pressure of 9 bar and is throttled to a pressure of 2 bar. The refrigerant then enters the heat exchanger, exiting at a temperature of 10 C with no significant decrease in pressure. In a separate stream, liquid water at 1 bar enters the heat exchanger at a temperature of 25 C with a mass flow rate of $ 2 \mathrm{~kg} / \mathrm{s} $ and exits at 1 bar as liquid at a temperature of 15 C . Heat exchanger can be assumed as adiabatic and kinetic and potential energy effects can be ignored. Determine (a) the temperature, $ T_{1} $ and $ T_{2} $ in $ C $, of the refrigerant. (b) the mass flow rate of the refrigerant, in kg/s (35p)

Source Material Used: Torricelli's theorem…also called Torricelli's Law, Torricelli's Principle, or Torricelli's Equation. Statement that the speed, v, of a liquid flowing under the force of gravity out of an opening in a tank is proportional jointly to the square root of the vertical distance, h, between the liquid surface and the centre of the opening and to the square root of twice the acceleration caused by gravity, 2g, or simply v = 2gh. Citation: "Torricelli's theorem." Encyclopaedia Britannica. 2005. Encyclopaedia Britannica Premium Service. Web. 4 Jan. 2005. Student Usage: Last week on my family camping trip to the lake, I realized that liquid, gravity, and vertical distance were all related mathematically, as can be seen by v=2gh.

Have you ever wondered how antibiotics actually work? They can differentiate your human cells from bacterial cells. Penicillin prevents bacterium from building a cell wall; animal cells do not have cell walls. The first antibiotic (penicillin) was discovered in the 1920s by Alexander Fleming. It wasn’t until the 1940s that it was commercialized. The delay was caused by difficulty in producing appropriate quantities. By the time it was commercialized, Methicillin-resistant Staphylococcus aureus (MRSA) was identified as resistant. In fact, when accepting his Nobel prize, Fleming cautioned the scientific community on antibiotic resistance. In 1959, resistant Shigella showed resistance to tetracycline. In 1962, MRSA was found to be resistant to methicillin. This same bacteria developed resistance to linezolid in 2001, vancomycin in 2002, and ceftaroline in 2011. Ceftaroline was only on the market for one year before resistance was identified. According to the Center for Disease Control (CDC), 23,000 deaths have been caused by antibiotic resistance (CDC, 2018). Does antibiotic use on livestock affect human health? If so, should it be restricted? Present your fact-based opinion and discuss the societal impact of antibiotic resistance. Furthermore, investigate the facts on both sides, and form your own defensible opinion. Validate your side with supporting details.
