A sprayer located in the vertical plane is used to deflect water with a mass flow of 30 kg/sec from a horizontal pipe by accelerating it by 45 degrees upwards. The elbow throws water into the atmosphere. The pipe diameter of the elbow at the inlet is D1=15 cm, and at the outlet is D2=5 cm. The Dec difference between the axes of the input and output sections is 40 cm. The mass of the elbow, along with the water contained in it, is 50 kg. Determine the necessary force to hold the elbow in place. The momentum flow correction coefficient for the fluid entering and exiting the control volume is 1.03. Note: The sections (1) and (2) are close enough to each other. Specific mass of water : ?w=1000 ??/?3
