Inclination angle of the conveyor () = 5 0Coefficient of friction (f) = 0.02Start-up factor (Ks) = 1.5Drive efficiency (Kd) = 0.9Friction factor (Cr) = 15Breaking strength loss factor (Cv) = 0.75Calculation:First, we will use the eqn.1.2 for finding out the load due to idlers:mi = (20/1.2) = 16.67 Kg/mWe will use the eqn.1.1 for finding out the belt tension in steady state:Tb = 1.37*0.02*250*9.81*[16.67+ {2*25+ (416.67/1.5)}*cos (5)] + (20*9.81* (416.67/1.5)) = 77556.88 N.The belt tension while starting the system can be calculated by using the eqn.1.4:Tbs = 1.5 * 77556.88 = 116335.32 NFor calculating the power at drive pulley, we will use the eqn.1.3:Pp = (77556.88*1.5)/ 1000 = 116.335 KwWe will use the eqn.1.5 estimate the size of the motor:Pm = 116.35/0.9 = 129.261 KwWe will use the eqn.1.6 to find out the acceleration of the motor:A = (116335.32 - 77556.88)/ [250*{(2*16.67) + (2*25) + (416.67/1.5)}]= 0.429 m/sec2Lastly, we will use the eqn.1.7 to find out the belt breaking strength:Bs = (15*116.35) / (0.75*1.5) = 1551.33 N/mmThis Bs value is used to select the conveyor belt from the manufacturers catalogue.ConclusionThe conveyor belt calculations methodology discussed in the article is to be used only for the guidance on calculating the initial conveyor design parameters; the final design must be validated by using the FEA or other similar tools before building the prototype.ReferenceDunlop Conveyor belt technique design and calculationBridgestone Conveyor Belt Design Manual

The impacts of GHG warming of the atmosphere are far more complex than a simple across-the-board warming of all regions to the same extent. Because of atmospheric circulation patterns, regional topography, and the relative position of land and sea in different parts of the globe, both the current observed temperature changes and predicted future changes show some startling differences in regional warming patters. The region most greatly affected by global warming is the Arctic. Again, the fossil record from this region confirms this pattern during pervious warm periods. While the middle latitudes might average 1C warmer in response to a global warming event, the Arctic may warm by 45C. This is discussed more fully in the article, Greatly Increased CO2 (Elias)
