To manually calculate your power consumption, all you need is this simple formula: Calculate the watts each device uses per day; Convert watts to kilowatts. There are 1000 watts in one kilowatt. Determine the kilowatts an appliance uses per month. Figure out the cost by multiplying the kilowatts per month by your electric rate. To start you'll need the device's wattage and an estimated ...

Water Hammer

Water Hammer

+

Water hammer in a piping system is caused by highenergy fluid transients and is easily identified by the sound that can be compared to the sound of a series of hammer blows to the pipe (see Figure 10). The magnitude of the transient is a function of the fluid properties, change in velocity, and modulus of elasticity of the pipe. The transient condition results in a pressure .
