to solve, you need only know or refer to the volume of a sphere and recognize that you can treat the ball as such for purposes of a physics problem. this volume is given by the formula v 4r 3. since the ball is 2 m across, its diameter is 2 m, and its radius therefore is 1 m. the volume of this ball is therefore 412 4 m 3, or 12

If you have any requirements, suggestions and comments on our products, please leave a message! You will be replied as soon as you see the information. Thank you! • ### calculating grease quantity frequency

2 the result will be grease quantity in grams. this formula works for all bearings and is widely accepted as the best way to calculate grease quantity. once the required grease volume has been calculated, you will need to determine how often to apply that amount of grease. this timeframe is known as the regreasing frequency

• 2011-11-9loading considerations when paralleling transformers it can be seen by using equations 1 and 2 below, that if the percent impedances in each transformer are the same, as shown in figure 1, that there will be equal current division and load sharing on each transformer

• ### formulas for gear calculation

2014-6-27the materials of 700 cm 3 volume sample with the balls was charged to the ball mill and ground initially at 100 revolutions. the ground sample was screened wit h the test sieve and the undersize sample was weighed and fresh unsegregated feed was added to the oversize to bring its weight back to that of original charge. t he numbers

• 2016-11-15ideally for a range of end mill hss cutter diameters. i am trying to calculate my estimated feed rate ipm using rpm x chip load x of flutes. but i have no chip loading charts or formula to work from, and i have no idea who manufactured my collection of hss end mills so cannot go to them

• ### lubricant application grease volumes and frequencies

2019-10-17to-use for frequency and volume calculation. option 1michael neale method. this approach pro-vides the volume in grams per hour. figures 1 and 2 may be used to calculate the grease replacement volume. the in-formation required is generally easy to obtain. requirements include bearing dimensions, shaft speed and diametrical clearance

• ### volume and weight calculator

calculate the volume and weight, in english or metric units, for over 40 geometric shapes and a variety of materials. select from such metals as aluminum, cast iron, or steel, or from such thermoplastics as abs, nylon, or polycarbonate. typical values for density are provided, but may be changed to accommodate more specific materials

• ### bearing life calculation

e 3.0 for ball bearings, 103 for roller bearings combined radial and thrust loads. all ball bearings, tapered roller bearings, and spherical roller bearings are capable of taking a significant axial thrust load. the equivalent bearing load, p, used in the rating life formula, needs to be calculated when combined radial and axial loads

• ### tubular rod mills

figure 8.2 shows a flow sheet where the rod mill is in open circuit and the ball mill is in closed circuit with a classifier. this is a normal set-up as the primary function of a rod mill is to provide a uniform sized feed to the ball mill. figure 8.3 shows that the rod mill product is classified and a more uniform feed size is, therefore, discharged to the ball mill whose primary function is

• ### how to determine the formula to calculate depth

it depends on how you are defining depth. for example, if you have a rectangular box which is 2m wide and 3m long, you will need to know the volume to calculate the depth- volume length x width x depth therefore- depth volume length x w

• ### this tool will calculate the deflection of profiles under

the deflection calculator provides several engineering specifications such as the moment of inertia and yield strength to determine deflection. you also have options depending on the expected configuration of your solution whether there will be one fixed end, two fixed ends or

• ### how to calculate cubic meters

to solve, you need only know or refer to the volume of a sphere and recognize that you can treat the ball as such for purposes of a physics problem. this volume is given by the formula v 4r 3. since the ball is 2 m across, its diameter is 2 m, and its radius therefore is 1 m. the volume of this ball is therefore 412 4 m 3, or 12

• ### ten steps to an effective bin design

volume depends on the volume lost at the top of the cylinder due to the bulk solids angle of repose, as well as the volume of material in the hopper section. because this design pro-cess is iterative, a reasonable estimate for cylinder height is sufficient at this point. try

• ### how to calculate the weight of steel

you can calculate the weight of steel by using the weight equation w mg for the weight w in newtons, mass m in kilograms and gravitational acceleration constant 9.8 ms 2.the mass of an object measures the amount of matter an object contains while weight is the force that the object exerts on the earth due to gravity
