The friction coefficient was measured while varying the rotational speed of the glass ball from 0.1 to 1000 rpm corresponding to 0.47 mm s 1 to 470 mm s 1 in 4.3 min, followed by 4.3 min during which the rotational speed decreased from 1000 rpm to 0.1 rpm.Friction coefficients at a rotation speed below 10 rpm were neglected due to.
Read MoreA novel condensing reactor for conversion of co2 to methanol is characterized under forced convective conditions, both experimentally and by modeling.The goal of the study is to optimize the operation conditions and identify limitations of the reactor concept.Experimental results show that productivity is limited by reaction equilibrium and mass transport at high temperature 250 c.
Read MoreExample 3.3 a rubber ball of mass 0.2 kg strikes a rigid wall with a speed of 10 ms 1 and rebounds along the original path with the same speed.Calculate the change in momentum of the ball.Solution here the momentum of the ball has the same magnitude before and after the impact but there is a reversal in its direction.
Read MoreBall and roller bearings some of the most common designs of ball and roller bearings are shown in fig.5.5.The amount of misalignment that can be tolerated is a critical factor in design selection.Roller bearings have higher basic load ratings than equivalent-sized ball types.
Read MoreFor instance, the exact value of the speed of light is 2.997 924 58 108 ms, but for most purposes, it is adequate to round this off to 3.00 108 ms, and we will often employ this approximate value of the speed of light in our calculations.3 3 when rounding a number, the following rule is employed for example, in your handheld calculator if.
