a) The discharge of water through a 140 bend, is 30 litres/s. The bend is lying in the horizontal plane and the diameters at the entrance and exit are 200mm and 100mm respectively. The pressure measured at the entrance is 100 KN/m2, what is the magnitude and direction of the force exerted by the water on the bend? b) Comment on how frictional losses might be included in the above analysis.
