Question

A pump is used to fill up a rectangular tank with liquid methanol solution (density 900 kg/m³ and dynamic viscosity 1.20 x 10^-3 Ns/m²) through a 2.5 inch diameter pipe. The tank is 1.4 m wide, 1.6 m long and 1.2 m deep.

1. Estimate the volumetric flow rate (m³/s) in the pipe if the pump can move the methanol at a rate of 80.6 L/min through this pipe.

2. Estimate the average velocity in the pipe (m/s) if the pump moves the methanol at a rate of 1.01 x 10^-3 m³/s.

3. Estimate the mass flow rate (kg/s) in the pipe if the pump moves the methanol at a rate of 1.69 x 10^-3 m³/s.

4. Estimate the time to fill the tank in minutes if the pump moves the methanol at a rate of 1.10 x 10^-3 m³/s.

5. Estimate the total mass (kg) of Methanol in the full tank.

6. Estimate the Reynolds number of the flow in in the pipe if the average velocity in the pipe is 0.84 m/s
