In physics, you can calculate power based on force and speed. Because work equals force times distance, you can write the equation for power the following way, assuming that the force acts along the direction of travel: where s is the distance traveled. However, the object's speed, v, is just s True or false 1. Log in. Join now. 1 runs 12 meters and kicks the ball into the air. It lands 20 meters away from her. 2 meters before the ball lands it is 2. meters in the air. The flight of the ball is a parabola, what do we know about the parabola? 2 minutes ago A cuboid with volume 32cm3 has the height 4cm. Calculate the surface area. Surface area = 2lh + 2wh + 2lw . Previous. Next

24.04.2017You can calculate flow rates for air in different portions of a pipe or hose system utilizing the continuity equation for fluids. A fluid includes all liquids and gases. The continuity equation states that the mass of air entering a straight and sealed pipe system equals the mass of air leaving the pipe system. Assuming the density, or the compression, of the air stays the same, the continuity

In physics, you can calculate angular momentum in the same way that you calculate linear momentum — just substitute moment of inertia for mass, and angular velocity for velocity. What is angular momentum? Angular momentum is the quantity of rotation of a body, which is the product of its moment of inertia and its angular velocity. Linear momentum, p, is defined as the product of mass and

CALCULATE . Quick Links. Driving Time. Time Difference. Flight Time. Time Zones. Travel duration calculator. Travelmath provides an online travel time calculator to help you figure out flight and driving times. You can compare the results to see the effect on the total duration of your trip. Usually, the flight time will be shorter, but if the destination is close, the driving time can still

The ball position is stable because if the ball moves sideways, its outer side moves into a region of lower velocity and higher pressure, whereas its inner side moves closer to the center where the velocity is higher and the pressure is lower. The differences in pressure tend to move the ball back towards the center. Example 3 Suppose a ball is spinning clockwise as it travels through the air

26.09.2019You calculate Q by dividing the pressure drop across the channel ΔP by the polymer viscosity η, similar to the original equation for shear stress τ. This specific examples gives you another method of comparing shear rate vs. viscosity, and, through these methods of quantifying the differences in the motion of fluids, you can understand the dynamics of these phenomena better. Shear Rate and

ball, (HBW for tungsten carbide ball) but the qualification should be completed by indicating also the ball diameter (10 mm) and the applied force (load) (3000 kg). The complete and meaningful designation is therefore expressed as: 450 HBS10/3000 or 450 HBS10/3000. Note: ASTM Standardisation News of February 2000 announces that in the next future a change will take place, whereby steel balls

29.08.2018We believe it is important for technicians to understand the theory of air flow measurement, to recognize when a data point is unlikely to be correct, a false reading, or a calculation does not seem correct and should be double checked. In today's results-now environment, these new technologies speed the process along. Your experience will double-check the process, but this instrumentation

If an application operates under heavy loads at low speeds, load carrying tests such as four-ball EP or Timken OK load should be considered. It is important to remember that greases, like oils, have a careful balance of properties. A product may excel in one category and perform poorly in another.

How do you calculate the belt pulley ratio? The ratio in a drive system is represented in reference to the number 1. A ratio of 2 to 1 would be signified by 2:1. A ratio of 1/4 to one would be signified by .25:1. To find the total ratio, use the pulley ratio formula: Ratio = (Radius of Driven Pulley) / (Radius of Drive Pulley)

20.06.2018Imagine you're a scuba diver, and you need to calculate the air capacity of your tank. Or imagine you've blown up a balloon to a certain size, and you're wondering what the pressure is like inside the balloon. Or suppose you're comparing the cooking times of a regular oven and a toaster oven. Where do you start? All of these questions have to do with the volume of air and the relationship

(If air is the fluid medium, it usually is vented to the atmosphere.) Because the area of the rod-end piston face is smaller than the cap-end area, extension force is greater than retraction force (assuming equal fluid pressures). Because total cylinder volume is less with the cylinder fully retracted (because of rod volume) than when the cylinder is fully extended, a cylinder retracts faster

The two-compartment ball mill operating in a closed circuit with a high efficiency separator is thus still the most preferred arrangement for new cement grinding installations although the vertical roller mill now has emerged as a viable alternative to the ball mill system and has increased its share of the market for cement mills over the last decade. There are a number of explanations to

Ball Mill Power Calculation Example #1. A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps are as follows: Example Calculation. A motor with

The hand-mill gives you society with the feudal lord; the steam-mill society with the industrial capitalist. Marx, Poverty of Philosophy (1847) Economists explain how production takes place in the above-mentioned relations, but what they do not explain is how these relations themselves are produced, that is, the historical movement which gave them birth. M. Proudhon, taking these relations for
