    Calculating Water Flow Rate Under Compression

    I would like to know how to calculate the flow rate of water under compression by a hydraulic weight. How do you calculate using the value of the weight on top of the water and the height of the water in a straight column?

    Gravity’s Effect on Water Flow from Tap??

    water from tap... A tap is left slightly open., and a gentle stream of water is flowing downwards from it. Why is it that the stream becomes thinner as it gets farther away from the tap? ??

    Understanding electromagnetic water flow meters

    You may know that water flow can be measured by an electromagnetic flowmeter. A strong magnetic field is applied perpendicular to the flow. An electric field is measured in the third direction. It seems to work just like a dynamo, which I understand, at least I believed that. But why...

    Bernoulli's Equation on water flow

    Water flows through a horizontal pipe and then out into the atmosphere at a speed v1 = 19 m/s. The diameters of the left and right sections of the pipe are 4.3 cm and 2.1 cm, respectively. (a) What volume of water flows into the atmosphere during a 16 min period? In the left section of the pipe...

    Water Flow Discharge: Is My Thinking Correct?

    I've got two tubes filled with liquid, their both of equal diameters, the first one is straight up and down about 20 feet long, the other is 100 feet long but is spiraled like on a spool, since the straight tube has a higher fall than the spiral, I would assume that the straight tube would have...

    Calculating Water Flow at 25mph: A Pool Design Challenge

    does anyone know how i could go about calculating how much power is needed to move 1,972,080 gallons of water at a constant rate of 25mph or 475,200,000 ft/s?...my friend and i are trying to figure out how to draw up a pool of water that would do this and i don't know how i could go about...

    How Long to Drain a Cubic Mile of Water Through a One Square Inch Opening?

    Neglecting evaporation, if you have a cubic mile of water (1 mile by 1 mile by 1 mile) how long would it take to drain if at the bottom there is a one square inch opening? I am verifying my answer with some really bright people. You

    Tap Water Flow Reduction: Why Does Distance Matter?

    Hi, Please could someone explain why it is that the cross section of water emerging from a tap decreases with tap distance ... is it due to air resistance acting to form some kind of aerodynamic shape? any thoughts would be much appreciated!

    Fluid Mechanics: Solving 8 Min Water Flow Problem

    This is the last problem with fluid mechanics and I have no clue about this one... any ideas? Water flows through a horizontal pipe and is delivered into the atmosphere at a speed of v1=15.9 m/s. The diameters of the left and right sections of the pipe are 8.5 cm and 2.5 cm, respectively. (a)...

    Calculating Water Flow Speed at Points A and B: Pipe Branching Equations

    I've struggled with this since this morning with hardly any progress. "There is a level pipe filled with water flowing through it. Branching off from this pipe are two pipes going perpendicularly upward, with a cross sectional area Sa, Sb, respectively, and there being a difference in water...

    Understanding Water Flow Dynamics in a Bernoulli's Pipe

    Hi everyone….I have a new question. I am writing a lab write-up and I am kind of confused about a concept. In this lab I studied the even flow of water by analyzing the flow of water through a Bernoulli’s pipe. The pipe was set up in a way that it was vertical, open at the top (where a hose...

    Is Bernoulli's Principle of Water Flow Really Flawless in Hydraulic Engineering?

    For fourty years the Bernoulli terms of H+Z+v^2/2g = K offered me a seemingly perfect tool for hydraulic engineering. Suddenly the wheels have fallen off this wagon because v^2 in a STRAIGHT line has a potential equivalence of H... v^2 in a CIRCULAR path has 2H equivalence ? A Newtonian...
