Calculators and their importance in science
It is no secret that science has made our life easy. Science and technology have given us an apparatus that has made our life easier and this device is nothing but a calculator. With the help of calculators, we can perform lengthy calculations within seconds.
We can get the exact value of a mathematical equation. Taking the exact value in the equation is very important in the case of scientific calculations. Otherwise, our objective will not be fulfilled. So, let us have a look at some equations that can easily be calculated by using a calculator:
Peng Robinson equation:
The Peng Robinson equation is an important term in thermodynamics. It is used to determine the entropy of a fluid mixture and the purity of a substance; this equation plays a major role in physics. The equation is denoted by p=[R.T/(Vm – b)] – [aα /.(Vm2 + 2 Vm .b - b2)]
Where,
p= pressure
Vm= Relative volume
t=temperature
R=molar gas constant
a= peng Robinson constant
b= peng Robinson constant
When it is calculated by hand, it is difficult to calculate the accurate value but when it is calculated using the peng robinson calculator, it is easy to calculate.
Logic Gate:
Making a truth table in binary is an important job to do. Unless you are an electronics expert, logic gates are one of the basic things to be done in electronics. To avoid any error in the truth table, one can run the value on the Logic gate output calculator and get the proper truth table for the logic gate output
Prandtl number :
The Prandtl number is the ratio of the same physical quantity. That's why it is a dimensionless number. It acts as a constant in thermodynamics. The Prandtl number is denoted as Pr. The right formula for Prandtl number is Pr= V
Where , v = momentum diffusivity (m2/s)
α = thermal diffusivity (m2/s)
This formula can be calculated using the Prandtl number calculator easily.
Transient thermal conduction :
The transient thermal conduction solver deals with the kind of heat transfer between substances that are in direct contact with one another. Heat exchange by conductivity may be utilized to point out heat loss through a barrier.
The formula to calculate conduction heat transfer is
Q=KA(T1-T2)/d
Where,
Q = Conduction heat transfer (W)
K = Materials thermal conductivity (W/mK)
A = Cross-sectional area (m²)
T1=higher temperature
T2=Lower temperature
d=material thickness
Final Thought:
Using scientific calculators, you can calculate any physical quantity you want to. These calculators can be used for concentric tube heat exchanger calculation. Yes, we can definitely do the calculations The process is done within a few seconds.
