What is Mechanic of fluids: Definition and 15 Discussions

Instrument mechanics in engineering are tradesmen who specialize in installing, troubleshooting, and repairing instrumentation, automation and control systems. The term instrument mechanic came about because it was a combination of light mechanical and specialised instrumentation skills. The term is still is used in certain industries; predominantly in industrial process control.

    Water Pressure and 2 dimensional motion

    $$ H = \frac { V^2 - V_0^2 sin \Theta} {-2g} $$ $$ H = \frac {V_0^2 sin \Theta} {2g} $$ So, I need to calculate ## V_0 ## I'm thinking about pressure. $$ P = \rho g \Delta h $$ $$ \Delta h = h - L sin \Theta $$ $$ F_A = P S_A $$ $$ F_A = P S_B $$ Dead End here...

    B What property of a fluid determinates rising and sinking Velocities

    If we have a bottle with a fluid A of X density, and in the bottom of this bottle it magically spawns the same amount of fluid B with X/2 density, fluid B should rise in fluid A until they both change positions and fluid B floats in A. Wich property of the fluids are the ones that determinates...

    Python Wave on string: How can I create a traveling triangle pulse?

    I have the following program that moves a wave on a string with fixed ends. The program solves the wave equation given a initial condition wave. The initial condition is a triangle wave splitting into two pulses. Here is the code written in Python: from numpy import * from matplotlib.pyplot...

    Why plucking of string creates two pulses?

    When we pluck a string and a triangle is formed. Why does this triangle form into two opposite moving pulses? If we have reflective edges the two pulses will reflect, invert and superposition into the same triangle wave on the under side of the string. Let's say we have no dampening. I think...

    Where can I find tech specs for prosthetic heart valves

    So I am doing a project for an advanced fluids class where I plan to do a CFD analysis of two different prosthetic heart valves, the bi-leaflet valve and the ball and cage (star-edwards). I cannot seem to find the technical specifications or drawings that I need in order to make a good cad...

    I Confusion Over Hydraulic Gradient, L parameter

    I've come across two different approaches to quantifying what l is in the equation for hydraulic gradient Δh/L. In this first picture L is the parallel distance along the datum across the reference plane But in this second picture L is the length along the pipe Why are the two L's...
