Hydrodynamics Definition and 59 Threads

If I have some water in a thin (on the order of micrometer or nanometer even) cylinder, a meniscus will form due to hydrodynamics and surface tension effects. There will be some characteristic height of the meniscus above the surface of the "bulk" water. Let's call this height "h". If I make...

Hi, hope this is the right area. Also please excuse me completley ignoring the template, I don't think it's applicable for the problem. I'm an honours year student in a comp sci course and I've decided to do an implimentation of Smooth Particle Hydrodynamics in a 3d application as my topic...

hey guys, urgently need your help, I am an industrial design student and at present we have a project that involves designing and constructing a peddel powered water craft. there will be a race upon completion of the craft therefore it needs to be reasonably fast. If you have any...

Hi fellas 1. Homework Statement a wooden stick , length 4 meters , density = 600 kg/m³ and thickness = 225 cm² is attached on a hinge 1 meter above water so the point is u got to find the angle the stick makes with the horizontal water you will see the drawing in the jpg file 3...

Homework Statement The water supply of a building is fed through a main pipe 6.00 cm in diameter. A 2.00-cm-diameter faucet tap, located 2.00 m above the main pipe, is observed to fill a 25.0-L container in 30.0 s. (a) What is the speed at which the water leaves the faucet? (b) What is the...

Sir, A tank is filled with water (density 1000 kg/m^3) and oil(density 900 kg/m^3). The height of water layer 1 metre and that of oil layer is 4 metre. If g=9.8 m/s^2, then what is the velocity of efflux from an opening at the bottom of the tank? I solved it the following way. Let d1 be...

Hi, Let's tie a sphere, drop it into a water and trawl it with a boat. How do we calculate the angle between a vertical line and rope? Actually I don't know much about aerodynamics and hydrodynamics so I don't know how drag force is calculated from shape, mass and speed of an object. Recently...

im supposed to predict height as a function of time for water leaving an orifice. determine heaigh as a function of drain time experimentally and compare the two on the same graph. i don't even understand what it wants. I am pretty sure I've got all the necessary data, but i don't know how...

Ok, I edited the post to show all my work, so here it is... A hole is punched at a height h in the side of a container of height H. The container is full of water. If the water is to shoot as far as possible horizontally, (a) how far from the bottom of the container should the hold be...
