This CGI script allows your visitors to calculate their percentage of body fat based on various skinfold measurements. This is a great way to add content to your health or fitness web site. The accuracy of skinfold bodyfat testing is largely based on the accuracy of the measurements and calipers are recommended.
This calculator is used to calculate pipe friction losses for straight piping handling water and water with varying percentages of ethylene glycol. The calculator uses an algorithm developed from the basic principles of fluid mechanics. This calculator allows the user to input the fluid type, the fluid temperature, the flow rate, the pipe size, pipe length, and pipe material. The calculator then determines the velocity, the Reynolds number, the Moody friction factor, the pipe friction factor, the pipe head loss, and the pipe friction loss in PSI.
