Orifice and Venturi Flow Meters Identify the independent and

Orifice and Venturi Flow Meters:

Identify the independent and dependent variables in this venturi and orifice .

What method did we use to control each independent variable?

What method did we use to measure each independent variable?

What method did we use to measure each dependent variable?

Estimate the uncertainty in each measured (independent and dependent) variable. Consider at least one systematic and one random error source.

Propagate the uncertainty in these measured variables through the computed results.

Was uncertainty in the measured variables the cause of the greater than unity venture discharge coefficient?

1) independent variables are feed flow rate and flow network.

dependent variables are cross-sectional area of the path and pressure head.

2) independent variables are controlled through the application of continuity equation by a simple valves

3) we can measure the feed flow rate by rotameter

4) preaaure head is measured by using manometer and area of the pipe is adjusted using continuity equation.
