Given James' golf ball has a radius of inches, and the height of the spherical cap that Jack cut off is inches, the volume can be calculated as follows: volume = 1/3 × π × 2 (3 × ) = in 3. Unfortunately for Jack, James happened to receive a new shipment of balls the day before their game, and all of Jack's efforts were in vain. Conical Frustum. A conical ...

Mill scale is one of waste materials which is produced as a result of hot rolling of steel in all steel companies. On the other hand, mill scale is considered a rich iron source with minimum impurities. This work aims at conversion of mill scale by adjusting smelting processes to produce different valuable products. The smelting processes were carried out using carbothermic reduction in a ...

how much kg of balls can be used for 20 kg ore in ball mill. In contrast, ball mills, rod mills and other tumbling mills are only partially of ore in a ball mill using 9 mm balls, but only 40 kWh/t in an IsaMill using a 2 in those days, cost about US25 per kilogram ("kg") and lasted for only a few hundred hours. China Millling of Sample Preparation Manufacturers and . Powteq ''s milling ...

· It is 40 hundredths of 20, so if we divided 20 cookies into 100 even parts (good luck with that!), 40 of those parts would be 40% of 20 cookies. Let's do the math: 40/100 * 20 = 8. A handy little tip: to divide by 100, simply move the dot two spaces to the left. In our calculation, 40/100 * 20 could be done as (40 * 20)/100 (it's the same thing). 40 * 20 is 800. By moving the dot in 800 by two ...

Have you ever wondered why some balls bounce higher than others? A ball's ability to bounce has a lot to do with its elasticity. So what is elasticity? It's an object's ability to return to its original shape after being stretched or squeezed. Objects that are more stretchy are usually more elastic, too. Do you have pajama pants with elastic material in the top? You can stretch to get ...

Example (1): 500 kg of the inert solid containing 28 percent by mass of the watersoluble component (A), is agitated with 100 m3 of water for 600 sec. After each decanting 25% of the solution produced remain in the residue. Water is saturated with the solute at a concentration of kg/m3. Find the concentration of the solute (A) in the solution after the leaching and number of washing such ...

1000 kg = 1 CBM. AIR CARGO KG to CBM. Calculating CBM for air cargo is different than for ocean freight. The standard formula used is length (cm) x width (cm) x height (cm) ÷ 6000 = volumetric weight (KG)/1 CBM ≈ KG. Any calculation for air freight will use this conversion, so it's worth noting this rule of thumb: 167 kg = 1 CBM

ball = ⎛ ⎝ kg ⎞ ⎠( m/s)= kg·m/s The ratio of the player's momentum to that of the ball is pplayer () pball = 880 = Discussion Although the ball has greater velocity, the player has a much greater mass. Thus the momentum of the player is much greater than the momentum of the football, as you might guess. As a ...

Ans. W = F × d = 25 N × m = 50 J 2. A force of 120 N is applied to the front of a sled at an angle of above the horizontal so as to pull the sled a distance of 165 meters. How much work was done by the applied force? Ans. W = F •d cos = 120 N • 165 m cos = 17, J 3. A sled, which has a mass of kg., is sitting on a horizontal surface. A force of 120 N is applied ...

In most countries where water power is used mills have been the firs usage. Originally the water wheel drove the millstones directly. Modern microhydro power (MHP) plants use Turbines instead of water wheels and mostly power a generator to produce electricity. But in cases where machinery can be used and installed near the turbine direct driven systems have some advantages . Such systems are ...

· 4 *N35875A0424* 5 Which of the following units could be used for power? A kg m s–2 B kg m2 s–2 C kg m2 s–3 D kg2 m2 s–3 (Total for Question 5 = 1 mark) 6 A ball is thrown straight up in the air and caught when it comes down. Which graph best shows the velocity of the ball from the moment it is released until just before it is

For soil, 1 ppm = 1 mg/kg of contaminant in soil, and 1 ppb = 1 ug/kg. A measurement of 6 mg/kg is the same as 6 ppm or 6,000 ppb, which is equal to 6,000 ug/kg. Concentrations in Water Concentrations of chemicals in water are typically measured in units of the mass of chemical (milligrams, mg or micrograms, ug) per volume of water (liter, L, l). can be confusing. This brief is intended to ...

The ball weight used for adult male competition is used if there is variation in the ball size used for different ages or classes. The standard unit of measurement is sometimes ounces or pounds and other times grams. Whichever the case, the units are converted so that you can compare the weight in either unit. See also our list of ball sizes. Sport Ball Weights, Sorted from Lightest to ...

One MET can also be expressed as oxygen uptake of ml/kg/min. METs are used to estimate how many calories are burned during many common physical activities. How it Works. We will demonstrate how the calculator works with a simple example: Susan is a 70kg (~154 lbs) woman who walked her dog for exactly 30 min. According to the metabolic equivalent table, walking the dog corresponds to an ...
