Question 1 a) Explain using the concept of depth changes and specific energy why Bernoulli's equation cannot be used to derive the Hydraulic Jump formula. (10) b) Derive the Hydraulic Jurnp formula starting with the conservation of momentum that states Net Pressure Force is equal to Change in Mornentum using discharge per unit width i.e. /,9Y1 = P9(it — V2) where location 1 is upstream of the jurnp and location 2 is downstream.
