Methyl alcohol at 25°C (ρ = 789 kg/m³, μ = 5.6 × 10-4 kg/m∙s) flows through the system below at a rate of 0.015 m³/s. Fluid enters the suction line from reservoir 1 (left) through a sharp-edged inlet. The suction line is 10 cm commercial steel pipe, 15 m long. Flow passes through a pump with efficiency of 76%. Flow is discharged from the pump into a 5 cm line, through a fully open globe valve and a standard smooth threaded 90° elbow before reaching a long, straight discharge line. The discharge line is 5 cm commercial steel pipe, 200 m long. Flow then passes a second standard smooth threaded 90° elbow before discharging through a sharp-edged exit to reservoir 2 (right). Pipe lengths between the pump and valve, and connecting the second elbow to the exit are negligibly short compared to the suction and discharge lines. Volumes of reservoirs 1 and 2 are large compared to volumes extracted or supplied by the suction and discharge lines. Calculate the power that must be supplied to the…

- .NET Interactive Solving Sudoku using Grover's Algorithm We will now solve a simple problem using Grover's algorithm, for which we do not necessarily know the solution beforehand. Our problem is a 2x2 binary sudoku, which in our case has two simple rules: •No column may contain the same value twice •No row may contain the same value twice If we assign each square in our sudoku to a variable like so: 1 V V₁ V3 V2 we want our circuit to output a solution to this sudoku. Note that, while this approach of using Grover's algorithm to solve this problem is not practical (you can probably find the solution in your head!), the purpose of this example is to demonstrate the conversion of classical decision problems into oracles for Grover's algorithm. Turning the Problem into a Circuit We want to create an oracle that will help us solve this problem, and we will start by creating a circuit that identifies a correct solution, we simply need to create a classical function on a quantum circuit that…arrow_forward4) A fixed bed adsorption unit contains rigid (incompressible) silica particles with a diameter of 120 um and porosity of 0.3.
