Why do engineers use calculus?
There are lots of applications of calculus; for example: calculating maxima and minima, analyzing the shape of curves, calculating acceleration when you know the velocity, calculating velocity when you know the acceleration; calculating the area of figures; calculating the volume of 3D shapes; etc.
What is a calculating clock?
Calculating clock is the first known calculating device made by Wilhelm Schickard. This machine can perform the basic mathematical operation, but canÕt show too large result which is limited to six digits.
What calculating device was invented by the Chinese over 5000 years ago?
Abacus was the first calculating device invented by the Chinese.

How do you use math in values?
by counting and calculating
Would the condenser have more or less subcooling if the unit had an overcharge of refrigerant?
An overcharge of refrigerant in the system would typically result in less subcooling in the condenser. This is because the excess refrigerant can lead to higher pressures in the system, causing the refrigerant to be more volatile and reducing the amount of subcooling that occurs in the condenser.
How does an undercharge affect the subcooling of a TEV system?
An undercharge in a TEV system can lead to decreased subcooling. This is because the system won't have sufficient refrigerant to remove heat from the liquid refrigerant to lower its temperature below the saturation point. As a result, the subcooling value will be lower than desired, potentially affecting system efficiency and performance.
How do you check for super heat and subcooling?
tell me what is mean by super heat
What methods besides weighing and measuring are use for charging systems?
subcooling methods
What is the difference betwen r410 and r407?
R410A is a blend of hydrofluorocarbons commonly used as a refrigerant in air conditioning systems, while R407C is also a blend of hydrofluorocarbons used for the same purpose. The difference lies in their composition and performance characteristics, with R410A having a higher cooling capacity and energy efficiency compared to R407C.
How do you test a evaporator efficiency?
To test an evaporator's efficiency, you can measure the temperature and pressure of the refrigerant at various points in the system. Calculating the evaporator's heat transfer rate and comparing it to the theoretical maximum can also help evaluate efficiency. Additionally, analyzing the superheat and subcooling values can provide insight into the performance of the evaporator.
How do you calculate the subcooling in HVAC?
To calculate subcooling in HVAC, you need to measure the liquid line temperature and pressure. First, convert the pressure into temperature using a temperature-pressure chart. Subtract the liquid line temperature from the converted temperature to calculate the subcooling. Subcooling is important to ensure the liquid refrigerant leaving the condenser is cooler than its saturation point to prevent the formation of flash gas in the metering device.
The condensing pressure is 260 psig and the condenser outlet temperature is 108 degree F for R22. how many degree is the liquid subcooling in this system?
Liquid subcooling is the difference between the condenser outlet temperature and the saturation temperature of the refrigerant. For R22 with a condenser outlet temperature of 108°F at 260 psig, the saturation temperature is approximately 94°F, resulting in a liquid subcooling of 14°F.
What gas is used in air conditioner?
As of now, Air conditioner uses R22 refrigerant. In coming days ACs will come with refrigerants such as R410A, R407C etc.

What happening when you are overcharging an air conditioning with freon?
discharge pressure is high, suction pressure is high superheat is low and subcooling is high.
When was Calculating God created?
Calculating God was created in 2000.
