Does anyone know how to put the colebrook equation into the TI-89?
here is the equation:
1/sqrt(f) = -2log [(k/D)/3.7 + 2.51/(Re x sqrt(f))]
here is the equation:
1/sqrt(f) = -2log [(k/D)/3.7 + 2.51/(Re x sqrt(f))]
The Colebrook Equation is a mathematical formula used to calculate the friction factor in turbulent flow. It is commonly used in fluid mechanics and engineering to determine the pressure drop or head loss in a pipe or channel.
To enter the Colebrook Equation into your TI-89 calculator, press the "Apps" button, scroll down to "Equation Writer," and then select "Colebrook." Alternatively, you can manually input the equation using the "Catalog" button and searching for "Colebrook."
The Colebrook Equation requires three inputs: the pipe roughness coefficient (ε), the Reynolds number (Re), and the pipe diameter (D). These values can be obtained from the pipe specifications or through experimental measurements.
Yes, the TI-89 can solve the Colebrook Equation for any of the three variables: ε, Re, or D. You simply need to input the known values and leave the variable you want to solve for as the unknown.
The TI-89 is a powerful calculator and can handle complex equations like the Colebrook Equation. However, it is important to note that results may vary depending on the accuracy of the inputs and the calculator's precision. It is always recommended to double-check your calculations and use appropriate units for each input.
