<p>[QUOTE=&quot;zaneman, post: 107410, member: 3970&quot;]This contest is a bit tricky. All you have to do to win is be the first to answer this question. The price will be a 1915-s buffalo nickel and some other stuff as well. </p><p><br /></p><p>In order to win, as mentioned above, be the first to answer the question, but you must show the whole solution. It&#039;s a relatively simple problem. If no one answers within a week, I will post the solution. </p><p><br /></p><p>Question: A brewery uses a 1.5&quot; sanitary pipe with an internal diameter of 3.5 cm, and a length of 10 meters to feed the keg filling apparatus. At the end of each shift, the pipeline is CIP by circulated 80°C cleaning solution through the pipe. The solution has an average flow velocity of 5 m/s. Calculate the pressure drop in kilopascals due to friction forces across the length of the pipe.</p><p><br /></p><p><br /></p><p>Hints:</p><p>You will need to solve the mass and volumetric flow rate</p><p>Assume the solution has the same properties as water as far as viscosity and density.</p><p>You will need to calculate the reynoulds number</p><p>You will need to use a moody chart to determine the fanning friction factor</p><p>Equivalent roughness is 1.5x10^-6</p><p><br /></p><p>GOOD LUCK![/QUOTE]</p><p><br /></p>
