Mechanic of fluids Definition and 16 Threads

Well, I was trying to predict how much energy a pneumatic system would need in order to actuate in a specific force and speed, but it seems that I would need too little energy for too much work. So, I was wondering how I would go on about making a pneumatic system with artificial muscles, they...

I originally thought about working out the force F with which it pushes the water thru the tube using pressure, and after using impulse and momentum to get the initial velocity, but sadly it wasn't successful. If anyone can help, please.

Vc-volume of the water that came out Vall-volume of the water before leakage S-area of the glass bottle h-bottles high h1-height of air column before leakage h2-height of the air column after leakage hv,1-height of the water column before leakage hv,2-height of the water column after leakage...

According to the Joule experiment, work can increase the temperature of a liquid. Is it possible to boil water simply by stirring it? How much energy would be required?

Can anyone help me? I know that's wrong, but i don't know where. Thanks for your attention so far.

$$ H = \frac { V^2 - V_0^2 sin \Theta} {-2g} $$ $$ H = \frac {V_0^2 sin \Theta} {2g} $$ 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...

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...

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...

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...

Hello everyone, I need the following but I am not sure if it is possible or not? I don’t have mechanical engineering background. Please advise me on feasibility of this project and any suggestion would be greatly appreciated. I am looking to design a horizontal cylindrical hollow turbine...

< Mentor Note -- thread moved to HH from the technical physics forums, so no HH Template is shown >[/color] Hi guys, I'm an IT student 'and lill favour in my masters research work so please help me to have valid answers for following questions ASAP. 1. Do patient specific MRI contains the...

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'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...

Homework Statement The tank shown in the figure is located in a place with a atmospheric pressure (90 kPa abs). If X = 3.50 m, Y = 1.80 m and the vapor pressure of the alcohol is 13 kPa (abs), determine: 1) manometer reading "A" in KPa. 2) The height "h" of mercury manometer. Homework...

Homework Statement So the full problem is the following: "On the top of a truck, there is a cubic container with a side-lenght of 1,00 m and it's filled with 500 liters of water. The truck accelerates with 2.0 m/s2 in the x-direction during the whole experiment. When the watersurface has...
