The specific enthalpy, h, of liquid water at 20 P oC and 100 kPa. Need to interpolate in Table A-6 between state properties at 600 and 650 P oC.: 3338.2 3241.7 u 3241.7 650 600 620 600 u 3,280.3 kJ/kg c) The specific enthalpy of saturated liquid water at 100 kPa.

A gardener planted a tomato plant and she measured and kept track of its growth every other day. Interpolation Formula Excel Interpolation Formula ExcelHereвЂ™s an example that will illustrate the concept of interpolation. вЂ¦ A few data points from the original function can be interpolated to produce a simpler function that is still fairly close to the original. Includes interactive Mollier.In the mathematical field of numerical analysis, interpolationВ is a methodВ of constructing new data points within the range of a discrete set of known data points.

The technique of using linear interpolation for tabulation was believed to be used byВ Babylonian astronomersВ andВ mathematiciansВ inВ SeleucidВ MesopotamiaВ (last three centuries BC), and by theВ Greek astronomerВ andВ mathematician,В HipparchusВ (2nd century BC). Linear interpolation is an easy way to do this. Suppose that one has a table listing the population of some country in 1970, 1980, 19, and that one wanted to estimate the population in 1994.

вЂњBresenhamвЂ™s algorithmВ lerps incrementally between the two endpoints of the line.вЂќLerp operations are built into the hardware of all modern computer graphics processors. The term can be used as aВ verbВ orВ nounВ for the operation. In that fieldвЂ™s jargon, it is sometimes called a lerp.

If x xВ is closer to x 1 x1В then we use y 1 y1 as the estimate, otherwise, we use y 2 y2. The first is to see whether x xВ is closer to x 1 x1В or to x 2 x2. Call this y yВ value estimate вЂ” an interpolatedВ value.Two simple methods for choosing y y come to mind. Because this operation is cheap, itвЂ™s also a good way to implement accurate lookup tables with a quick lookup for smooth functions without having too many table entries.Read Also: What Are Alphanumeric Characters? Formula For InterpolationLet us say that we have two known points x 1 , y 1 x1,y1В and x 2 , y 2 x2,y2.Now we want to estimate what y yВ value we would get for some x xВ value that is between x 1 x1В and x 2 x2.

This is a linear interpolation. We look to see the y yВ value on the line for our chosen x x.
