It is not surprising that techniques developed for electrical networks are useful for hydraulic networks. Electrical capacitance is analogous to a tank, lake, pond, or impoundment. Electrical inductance has no counterpart in any element in chemical or environmental processes, although there are some analogies of pulsing flow of liquids to inductors with alternating currents. Some electrical devices do change resistance with current or with voltage. following code snippet prints a table of friction factors for /D 0.002 and for ve Reynolds numbers in the range 5000 Re 5 × 106. In most applications the ow is incompressible. A major difference is that hydraulic losses of potential are not linear with flow, while simple electrical potentials are usually linear as governed by Ohm’s law E = IR, where E is the EMF, I is the current, and R is the resistance. A is the cross-section area, and V is the average velocity. have a length of 800 m and width of 25 m, as all beams have rectangular cross. Please debug the matlab code for the Hardy Cross method for the following problem. Of course, the world-wide impact of Hardy Cross paper of 1932. The given problem showcases an application of concepts like Bernoulli approach, the minimum pressure in vena contracta, Cavitation, Hardy cross method. Hydraulic head is the counterpart of voltage (electromotive force or EMF), and hydraulic resistance is described by equations similar to those that govern electrical resistance. In chapter 1 some script MATLAB codes and Simulink models about the PID. method using a MATLAB code that rapidly converges on the correct answer for a laterally. Fluids flowing through pipes, through conduits, or in channels have much in common with electricity flowing through resistors.

Biochemical, environmental and chemical systems have analogies to electrical systems.
