DESCRIPTION: The total pressure of a flow decreases along a streamline due to losses associated with non-ideal affects. These losses can be broken into major and minor total pressure losses. In this experiment, the major and minor total pressure losses through a pipe outfitted with a gate valve will be determined using pressure taps drilled into the pipe surface. The total pressure losses will be used to calculate the flow's friction factor and the valve's loss coefficient for a variety...
Water at 5º C flows downwards in a vertical 2 mm diameter pipe. The pressure gradient is zero, that is, the flow is driven only by gravity. Compute the flow rate. _________________________________________________________________
5. Oil Flow in a Pipe Oil (S 0.80;0.01 lb s ft-2) flows downward in the pipe shown in Figure 3. The pipe diameter is 0.10 ft and has a slope of 30°. The mean fluid velocity is 3 ft s1.
