... Suppose valve has linear trim and flow must be increased. If p through exchanger did not change, valve would behave linearly (true for low flow rates), since it takes most of p. For higher flow rates, p through exchanger will be important, changing effective valve characteristics (valve must open ...

... Electricity is the flow of electric charge Electric charges can flow in wires, light bulbs, and even in salt water. In some ways, the flow of electric charges acts like the flow of water, so we will often make an analogy between electricity and water flow. Nonetheless, this is only an analogy. Elect ...

... Bernoulli's equation is used to solve some problems. It relates conditions (density, fluid speed, pressure, and height above Earth) at one point in the steady flow of a nonviscous, incompressible fluid to conditions at another point. If you are given all but one of these quantities you can use Berno ...
