Water flows into a tank and out through another pipe, as shown in the figure below. The water in the tank has a surface area, Asur f = 5.6 m². At the bottom of the tank there is a door inclined at an angle 25 degrees with respect to the horizontal. The door has a length L = 1.1 m and a width w=1 m (out of the page). The flowrate into the tank is Qi(t) = 0.26 m³/s and the flowrate out is Qo(t) = 0.05 m³/s At time t = = Asurf 0, the water has a depth ho = 2.5 m. The density of water is p = 1000 kg/m³. h(t) Qout

Can someone please explain the parts marked on the photo. Like why is there no two included in the other equation and the steps taken to find Poisson equation. Please actually show step by step including the calculations to find the final answer. Thanks

Water flows through a pipe as shown in the figure. The pressure at points 1 and 2 respectively is 1.85 × 105 Pa and 1.10 x 105 Pa. The radius of the pipe at points 1 and 2 respectively is 3.20 cm and 1.40 cm. If the vertical distance between points 1 and 2 is 2.75 m, determine the following. (a) speed of flow at point 1 m/s (b) speed of flow at point 2 m/s (c) volume flow rate of the fluid through the pipe m³/s P₂ y

If you decide to help, please help with all the parts of the question, I'm not sure I understand any of it... :/   The tank shown in the following figure is being filled by Pipes 1 and 2. The water level is to remain constant.   A tank of water is open at the top. The tank is filled from above by pipe 1 and pipe 2. Pipe 1 has diameter d1 = 1 in., and fills the tank with water at a velocity of V1 = 2 ft/s. Pipe 2 has diameter d2 = 1.25 in., and fills the tank with water at a velocity of V2 = 1.4 ft/s. Water empties from the bottom of the tank through pipe 3. Pipe 3 has diameter d3 = 1.5 in., and empties water from the tank at an unknown velocity V3. (a) What is the volume flow rate (in ft3/s) of Pipe 1? (b) What is the volume flow rate (in ft3/s) of Pipe 2? (c) What is the volume flow rate (in ft3/s) of water leaving the tank at 3? (d) What is the cross-sectional area (in ft2) of flow for Pipe 3? (e) What is the average velocity (in ft/s) of the water leaving the tank?
