Answer: When pressure increases, Temperature increases. When there is drop in pressure there is also a drop in temperature.
Explanation:
Forced air conditioning also known as central air conditioning unit uses a forces cooled through ducts into buildings.
Gay Lussac law states that the the pressure of a given mass of gas is directly proportional to its temperature provided volume is remains constant. How this relates to a the operation of a forced air conditioning unit is, Because the refrigerant is in closed cycle in the system it volume is always constant expect in a case where there is a leakage. As pressure increases in the system, This increase in pressure and temperature usually takes place at the discharge side of the compressor.
When pressure decreases in, so does the temperature in they system. This change or drop in pressure and temperature is noticeable when the refrigerant is returning back from the evaporator to the compressor through it suction outlets during the refrigeration cycle.
Answer: um wuh anyways thxs for the points!

Answer:
Inlet
Explanation:
Consider a laminar forced flow inside a pipe with constant wall temperature, the heat flux will have a higher value near the INLET of the pipe.
This is because the friction factor is experienced at the highest level when a laminar forced flow is at the tube inlet where the thickness of the boundary layer is zero. Also, the friction factor decreases step by step at a lower rate to the fully augmented value.
Answer:
Calipers
Explanation:
Calipers can also be used to measure holes of different shapes: square, rectangular, cylindrical or hexagonal. The lower set of jaws on the caliper is used to measure the outer diameter of a cylinder. It will also give you the total length or width of an object.
Answer:
h=27.15 KJ/kg
Explanation:
We know that ,Enthalpy of perfect gas depends only on temperature it did not depends on the volume and pressure.But on the other hand enthalpy of real gas depends on the temperature and pressure.
So specific enthalpy(h) is given as follows
For oxygen
From above
So
h=27.15 KJ/kg
