A 10 m3 tank is initially full. Water is added at a rate of 1 L/min (QIN) and is pumped from the tank at a rate of 2.6 L/min (QOUT).
a) Write the material balance equation for this situation

b) Solve the material balance equation to get an equation for volume as a function of time, V(t).

c) Determine how long it will take until the tank is half full.

    A tank initially contains 3 m3 of water at 15 ° C, which is heated by a coil that supplies 1,250 kcal / min. Water is fed to the tank at a rate of 300 L / min at 65 ° C and is discharged at 400 L / min. It considers a density of 1.0 kg / L for water and a Ĉp of 1.0 kcal / kg K. The agitator in the tank has a 5 HP motor....

    (1) A tank is filled with 300 liters (L) of contaminated water initially containing 3 kg of toxin. Pure water is pumped in to the tank at a rate of 40 L/min, mixes instantaneously, and the mixture is pumped out at the same rate (40 L/min). Let y(t) be the amount of toxin present in the tank at time t. Write the differential equation and the initial value that models this scenario. (a) Find the particular solution, y(t). Put a...

    Water is added at varying rates to a 400.0 -liter holding tank. When a valve in a discharge line is opened, water flows out at a rate proportional to the height and hence to the volume V of water in the tank. The flow of water into the tank is slowly increased and the level rises in consequence, until at a steady input rate of 50.0 L/min the level just reaches the top but does not spill over. The input...

    4. Suppose there are two tanks, each containing 200 l of fluid. Tank 1 initially contains pure water and tank 2 initially contains water with 200 kg of salt dissolved. The tanks are stirred constantly so their solutions have uniform concentration. There is a pipe which takes 10 l/min from tank 1 to tank 2, and another pipe which takes 5 l/min from tank 2 to tank 1. Also, pure water is being pumped into tank 1 at a rate...

    6. A 500 L tank initially contains 10 g of salt dissolved in 200 L of water. Water containing 1/4 g of salt per liter is poured into the tank at the rate of 4 L/min and the mixture is drained from the tank at the rate of 2 L/min. Find an initial value problem that solve for x(t), the mass of salt in the tank at time t prior to when the tank overflows, then solve for x(t).

    A cylindrical tank is being filled with water. The tank is initially empty but then water begins to flow into it at a rate of 62.00 kg/min. There is a small hole of radius r = 0.7000 cm at the bottom of the tank where water can escape. Because the flow rate of water leaving the hole is initially at a slower rate than water entering the tank, the water level rises. The average velocity of water leaving through the...
