ooo T-Mobile LTE 6:50 AM 104.197.195.53 73% A spherical tank has a circular orifice in its bottom through which the liquid flows out. The flow rate through the hole can be estimated as QV/dt-CA/2g where Qout outflow (m³/s), V-volume of the water remaining in the tank (m³), C-an empirically derived coefficient, A = the area of the orifice (m²), g = the gravitational constant (9.81 m/s²), and H- depth of liquid in the tank. Euler method to determine the amount (volume) left in the tank. When all the water is about to flow out of the tank, the flow rate goes to zero and remains in that state forever. Consider the tank diameter, D (2r)-2 m, initial height (H)=1.5 m, diameter of the orifice - 2.8 cm and C=0.55. Use the time step size of 30 s. Take #=3.1416. 1) Plot V vs t curve and sketch the exact on the paper. Enter the determined volume at 660 s. Attempts 07-19
