Document Summary
Pe + ke + eth + = etot. From chemistry: volume of a fluid inside a cylinder = cross sectionalarea height. V ol = a h measured in [m3] density of a fluid is : = v m ol. If we apply the density concept to the energy system from 7a we start our 7b material with the energy density equation : where : And we define this new quantity p= pressure = Then we get the energy density equation to be: Another quantity relevant of fluids is their flow rate defined as. Also i =av, where a is the cross-sectional area of the tube, v is the velocity of the fluid. I is constant in a fluid system (the amount of fluid entering the system is the same as the amount of fluid leaving the system): i = a1v1 = a2v2. The pipes/tubes are made of different materials and they can have friction.
