STEP 0: Pre-Calculation Summary
Formula Used
Pouring Time = Empirical Constant 1*sqrt(Mass of Casting)
tpt = K1*sqrt(W)
This formula uses 1 Functions, 3 Variables
Functions Used
sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)
Variables Used
Pouring Time - (Measured in Second) - Pouring time is the time for complete filling of a mould.
Empirical Constant 1 - Empirical Constant 1 is a constant value determined by experiments or It can vary depending on the specific casting material and they are derived from data obtained from casting operations.
Mass of Casting - (Measured in Kilogram) - Mass of Casting is the amount of material used to create the casting. It is an important parameter in casting processes.
STEP 1: Convert Input(s) to Base Unit
Empirical Constant 1: 1.82 --> No Conversion Required
Mass of Casting: 36.8 Kilogram --> 36.8 Kilogram No Conversion Required
STEP 2: Evaluate Formula

What is pouring time?

The time for complete filling of a mould is termed pouring time, is a very important criterion for design.Too long a pouring time requires a higher pouring temperature and too less a pouring time means turbulent flow in the mould, which makes the casting defect-prone. There is thus an optimum pouring time for any given casting.
The pouring time depends on the casting materials, complexity of the casting, section thickness and casting size. The various relations used are not theoretically obtained but established generally by the practice at various foundries and by experimenters.

What values can k take?

K1= 2.080 for thinner sections
K1= 2.670 for sections 10 to 25 mm thick
K1= 2.970 for heavier sections
