Atomic energy in cosmic and human life;: Fifty years of radioactivity

First released in 1945, within the aftermath of the bombing of Hiroshima and Nagasaki, Atomic power in Cosmic and Human existence bargains a distinct account of the matter of atomic power and the underlying ideas of radioactive decay. Written by way of the pre-eminent physicist George Gamow, and devoted to the desire of lasting peace, the e-book was once initially designed to offer an entire photograph of what atomic power is, the place it comes from, and the way it may be used for higher or worse.

Remember that you must also take into consideration the level of the water in the suction tank. If the water level is 10 feet below the pump suction connection then the static head will be 10 + 15 = 25 feet. Therefore the total head will have to be at least 15 feet plus the friction head loss of the fluid moving through the pipes. Figure 30 Static head. 12. What is friction head Friction head is the amount of energy loss due to friction caused by fluid movement through pipes and fittings. It takes a force to move the fluid against friction, in the same way that a force is required to lift a weight.

Copyright Fluide Design Inc. 41 I mentioned that we can measure head at the discharge side of the pump by connecting a tube and measuring the height of liquid in the tube. Since the tube is really only a narrow tank we can use the pressure vs. 31 to determine the discharge pressure. Alternatively, if we put a pressure gauge at the pump discharge, we can then calculate the discharge head. Figure 36 Discharge static head plus friction head equals pump discharge head. We can calculate the discharge pressure of the pump based on the total head which we get from the characteristic curve of the pump.
