A flat belt drive is required for a piston pump. The pump is driven bv a ( 40-mathrm{kW} ) electric moter running at ( 1300 mathrm{rpm} ) with a pulley of ( 230 mathrm{~mm} ) diameter. The pump pulley is ( 600 mathrm{~mm} ) in alamete. The friction coefficient is 0.75 , the density of the belt is ( 1150 mathrm{~kg} / mathrm{m}^{3} ) and the maximur permissible stress is ( 7 mathrm{MPa} ). The distance between pulley centers is ( 1.4 mathrm{~m} ). The belt thickness is ( 3.2 mathrm{~mm} ). Determine the required belt width.
