Everything you need to know about scientific calculators

In the 21st century, scientists are doing some ground-breaking work. These ground-breaking works are accumulative works of numerous experiments and calculations. These experiments and calculations are based on a lot of conditions and constants. To get the right value of these constants, it is very important to do the calculations precisely and that can only be done using a calculator. For example, a Dynamic Viscosity Calculator to calculate the value of dynamic viscosity. 

So, here we will be discussing some physical quantities that can be calculated using formulas as well as calculators. 

Pressure Drop:

In a pipeline, pressure drop can occur due to rough surface, turbulence, elevation change, friction inside the pipe, and many other factors. The common process to calculate pressure drop or head loss is the Darcy-Weisbach equations.

The pressure drop is denoted by J. It depends on the diameter of the pipe D, gravity g, friction factor f, length of the pipe l, and velocity of the flow. For a simple equation, it might not look difficult but in research, where many calculations need to be done, using a pressure drop calculator saves so much time. 

Thermal conductivity:

The thermal conductivity of a metal is denoted by. The equation for thermal conductivity is

λ =QL/A ΔT  where λ = Thermal conductivity

A = Area of the surface

Q = Amount of heat transferred

L = Distance between two isothermal planes

ΔT = Change in temperature

Using a Thermal Conductivity Calculator, it can be calculated in seconds. 

Heat transfer coefficient:

Heat transfer coefficient is needed while designing a device. It has a role in insulations and device manufacturing. It is denoted by h. 

The general formula to calculate the heat transfer coefficient is h=q/ ΔT 

where q is local flux density and T is the temperature difference. Also, other factors affect this coefficient but with the help of a heat transfer coeff calculator, this is too easy to solve. 

In flow chemistry, the name CSTR is very popular. The CSTR or continuous stirred tank reactor is used for making a homogenous mixture using solvent reagent and reactant. The output is normally identical and homogenous. But when two viscous liquids are mixed, the transient CSTR tank reactor gets too slow. It is equipped with an impeller and other mixing devices. To design this device, the measurement of heat transfer coefficient, pressure drop and dynamic viscosity, are equally important. 

Bottomline:

To perform any mathematical and scientific experiment accurately, scientific calculators are very important. They not only ease the whole process but also provide the correct value so that in the bigger picture, the error becomes negligible.
