Problem: You and your team are tasked with designing an around-coil system for an air-conditioning unit that will be installed in a hospital. The system must provide a controlled environment for the hospital's air-conditioning needs, ensuring that fresh air is brought in while exhaust air is expelled, without allowing contamination between the two airflow directions. The air-conditioning system will include two coils and two pumps (one duty pump and one standby pump) in a configuration that accommodates both exhaust and supply airflows. The system needs to comply with ASHRAE Standards, and ASME BPVC Section VIII, with attention to safety, reliability, and efficiency. The system will be used in a climate with moderate temperature variations, and its design will need to consider a range of operating and design specifications. Given data Desired Pressure in the Pipe: According to the (ASHRAE) standard for pressure drop limits. Pipe Diameter: Must comply with standard pipe diameter…

What does Pascal's law state? Multiple Choice The pressure applied to a confined fluid increases the pressure throughout by the same amount. The pressure applied to a confined fluid increases the pressure on the parallel surfaces. The pressure applied to a confined fluid is proportional to the volume of the fluid. The pressure applied to a confined fluid increases the pressure on the perpendicular surface.

What does a 1 ton refrigerant represent: a. The weight of the air conditione r b. The amount heat required to cool 1 ton of air in 1 hour c. The amount of heat required to melt 1 ton of ice at 0 degree in 24 hours d. The weight of the refrigerant used.

Which component is primarily responsible for the pressure in a cooling system? Select one: a. The thermostat b. The water pump c. The radiator cap d. The surge tank

QUESTION 5 A package of frozen fish sticks have different instructions when they are heated up on the stove as compared to using the oven. Stove: Heat over medium flame for 2 minutes. Then flip the fish sticks (turn them over) and heat them for another two minutes. Oven: Preheat the oven to 375 F. Put them on a metal baking sheet for 15 minutes. a. Explain why the instructions have you flip the fish sticks over when you're heating them with the stove, but not with the oven. the fish sticks touching the metal baking sheet will cook more than the top side of the b. If you follow the oven instructions, the side fish sticks. Explain why.

Ventilation: The plant must have adequate ventilation to prevent the buildup of oxygen gas, which can be flammable and cause potential hazards. Electrical equipment: All electrical equipment used in the plant must be designed for use in a hazardous environment. Structural requirements: The building must be designed to withstand the weight and pressure of the refrigeration and cryogenic systems, as well as the potential stresses caused by temperature fluctuations. Please elaborate it well, this is an indoor consideration when designing cryogenic plant. you can add more.
