A t-joint is another common piping component, typically used to combine or separate flows of fluid. This t-joint has two inlets and one outlet. We want to find the flow rate through the outlet and the force to hold the t-joint in place. The working fluid is water. One inlet, open to the left, is 6 cm diameter and receives water at a velocity of 4 ms ¹. The other inlet, open to the right, has a volume flow rate of 1 Ls¹ and a diameter of 4 cm. If the outlet has a diameter of 12 cm and faces upwards with regard to gravity, determine: (a) the velocity through the second inlet. [0.80 m s-¹] (b) the velocity through the outlet. [1.09 m s-¹] (c) the reaction forces (x, y directions) to hold the t-joint in place [x: -181.7 N, y: 1156 N] Losses due to viscosity are assumed negligible. The outlet discharges to atmosphere. The weight of the t-joint and the fluid within it are negligible.
