b. Write the expressions for delta_p and IV. V: volume, IV: volume current, k: turbulent flow factor, b: exponent in power law, A: tank cross section, h: water level, delta_p: pressure difference, p_a: ambient pressure.
c. Use the comparison of data and model to determine the flow factor in the simplified turbulent flow law
I_V = k·SQRT(delta_pR)
d. Demonstrate by combining the appropriate expressions that if we use the above flow law, the Bernoulli effect is included in the flow factor k. If we correct for this effect, what is the effective flow factor?
e. Calculate the Reynolds number for a few points. Should the flow be turbulent?
