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 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
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.
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.

Which is better vertical or horizontal condenser?
Hi.. For only filmwise condensation, horizontal position gives higher condensation coefficent than verical position. In case of condensation with subcooling in a shell and tube heat exchanger, condensation coefficient is higher with horizontal postion while subcooling coefficient is higher with vertical position. kal....
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.
What is the oldest calculating device?
When was Calculating Space created?
Calculating Space was created in 1969.
When was Calculating God created?
Calculating God was created in 2000.
Why is subcooling desirable?
It increases the efficiency of the system since the amount of heat being removed per pound of refrigerant circulated is greater. In other words, you pump less refrigerant through the system to maintain the refrigerated temperature you want. This reduces the amount of time that the compressor must run to maintain the temperature. The amount of capacity boost which you get with each degree of subcooling varies with the refrigerant being used. Subcooling is beneficial because it prevents the liquid refrigerant from changing to a gas before it gets to the evaporator. Pressure drops in the liquid piping and vertical risers can reduce the refrigerant pressure to the point where it will boil or "flash" in the liquid line. This change of phase causes the refrigerant to absorb heat before it reaches the evaporator. Inadequate subcooling prevents the expansion valve from properly metering liquid refrigerant into the evaporator, resulting in poor system performance.
