Viscosity is a measure of how easily a fluid flows. For example, honey has a higher value of viscosity than does water because if you were to pour water and honey side by side on an inclined surface, the water will flow faster. The viscosity of a fluid plays a significant role in the analysis of many fluid dynamics problems. The viscosity of water can be determined from the following correlation
Using Excel, create a table that shows the viscosity of water as a function of temperature in the range of 0 ºC (273.15 K) to 100 ºC (373.15 K) in increments of 5 ºC. Also create a graph showing the value of viscosity as a function of temperature.
If the centrifugal pump feeding cooled water to a series of water-cooled condensers breaks down, the head pressure of the vapor compression systems will decrease.
