Unformatted text preview: (a) Find the rise in static pressure between (1) and (2), HINT ANSWER (b) Find the loss in stagnation pressure (total head) between (1) and (2). Check your results by showing that in the limit R 1 /R 2 0, they reduce to the forms that apply to a jet issuing into an infinite reservoir. ANSWER (c) Provide a criterion for when the shear stress is indeed negligible, as we assume in the problem introduction. Express the criterion as an inequality between the shear average stress and some combination of the given quantities and the distance L between stations (1) and (2). The given quantities are the upstream flow speed V 1 , , R 1 and R 2 . Neglect gravitational effects. HINT ANSWER...
