What is the rate of evaporation formula used to calculate the speed at which a liquid changes into vapor?
The rate of evaporation formula is typically calculated using the equation: Rate of Evaporation (Surface Area of Liquid) x (Rate of Evaporation per unit area). This formula helps determine how quickly a liquid turns into vapor.
What is the evaporation formula used to calculate the rate at which a liquid changes into a gas?
Well, honey, the evaporation formula you're looking for is pretty simple: it's just the rate of evaporation equals the surface area of the liquid times the difference in vapor pressure at the surface and in the surrounding air, divided by the resistance to evaporation. So, if you want to know how fast that liquid is turning into a gas, you better get crunching those numbers!
Meaning of 'pi'?
Pi is a Greek letter. It is used in mathematics to represent the number 3.1416. One may calculate the circumference of a circle by multiplying the diameter by pi. One may calculate the area of a circle by multiplying the square of the radius by pi. Pi is actually a little less than 3.1416, but that's close enough for most applications.
Hypobromite is used to purify contaminated water. what is the formula for hypobromite?
The formula for hypobromite is OBr-.
What is the water evaporation rate formula used to calculate the rate at which water evaporates?
The water evaporation rate formula is typically calculated using the equation: Evaporation Rate (Area of Water Surface) x (Evaporation Coefficient) x (Difference in Vapor Pressure) / (Thickness of Air Layer).
The formula used to find the area of a circle is?
Area = (pi) (R)2
What is the formula used for finding area of a circle?
area= pie*(r^2) = πr2
What is the formula used to find the area of a sector?
area of sector = (angle at centre*area of circle)/360
What does the formula Pi r2 mean?
It is the formula used in finding the area of a circle which is pi times radius squared
What is the formula used to find areaof a circle?
Area in square units = pi*radius2
What is the constant used in the formula to find the area of a circle?
You are thinking of pi.A = (pi)r^2
What is the area of a circle with a radius of 9 inches?
The formula for the area of a circle is: A = π r²If you use 3.14 for π, the formula would be:A = 3.14 x 9²A = 3.14 x 81A = 254.34 square inchesThe answer will vary depending upon what is used for pi. An online calculator for the area of a circle gives an answer of 254.469.
Differences between a numeric value and a formula?
A formula is used to find the numeric value of an answer. For example: pi*radius2 = area of a circle in square units
How is the formula of a polygon closely related to the formula of the area of a circle?
The area of a polygon is greater than the area of the largest circle that can be inscribed within the polygon and smaller that the area of the smallest circle in which the polygon can be enclosed. So the areas of two circles establish a lower and upper bound to the area of the polygon. In a similar fashion, the perimeter of the polygon are also bounded by the circumferences of the two circles. This also works in reverse. That is, the area of a circle lies between the area of an inscribed polygon and that of a polygon containing the circle. And, again, the same applies to the circumference/perimeter. In fact these bounds were used to calculate the value of pi.
The value of pi related to circle?
It is used to work out the area of a circle by using the formula πr2 and the circumference (Perimeter) πd. πr2 - Area: Pi x Radius2 πd - Circumference: Pi x Diameter π = 3.1415...
