Theoretically, the terminal velocity of steel ball with diameter 317mm in water is about 37m/s But in my experiment, it is only 07m/s The difference is really huge And also, I got a graph of terminal velocity as a function of square of radius of steel ball It is a straight line, but it does not go through origin Can anyone help me with that?

During air cooling of steel balls, the convection heat transfer coefficient is determined experimentally as a function of air velocity to be formula458mml m/s, where h and V are in W/m2âˆ™K and m/s, respectively Consider a 24-mm-diameter steel ball initially at 300°C with a thermal conductivity of 15 W/mâˆ™K

Mechanism and Types of Convection During air cooling of steel balls, the convection heat transfer coefficient is determined experimentally as a function of air velocity to be h = 179 V 054 for 05 V 2 m/s, where h and V are in W/m 2 K and m/s, respectively Consider a 24-mm-diameter steel ball initially at 300°C with a thermal conductivity of 15 W/mK

Density = mass/volume let us say the mass of the steel ball and the ship are same but the steel ball is fully enclosed, a tight spherical volume, where as the ship is a hollow, occupies more .

Jun 27, 2008· The radius of the steel ball is r = 2cm = 002m and its specific heat is c = 0486kJ/kgK Analyzing the units of these given values, I thought simple unit analysis would work For example, 1/c would give units of kgK/kJ The volume of the ball is v = (4/3)pi(r)^3 which has units of m^3 I'm having a difficult time trying to relate these things and manipulate them to just get the mass of this ball

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing rac The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads It achieves this by using at least three races to contain the balls and transmit the loads through the balls

The \maglev" experiment is a magnetic ball suspension system which is used to levitate a steel ball in air by the electromagnetic force generated by an electromagnet The maglev system consists of an electromagnet, a ball rest, a ball position sensor, and a steel ball The maglev system is

Louie tried to prove that he had balls of steel by entering the boxing ring without wearing a protective cup, but then ended up losing his ability to reproduce when his opponent violated the standard universal boxing rules and uppercut him REALLY hard in the groin Damn, this guy should be felt sorry for! That shit must've hurt like a living hell!

Newton's cradle is a device that demonstrates conservation of momentum and energy using a series of swinging spher When one sphere at the end is lifted and released, it strikes the stationary spheres, transmitting a force through the stationary spheres that pushes the last sphere upward
