Water flows in a 2 -ft-diameter duct under the following conditions: \(p_{1}=55 \mathrm{psia}\) and \(V_{1}=20 \mathrm{ft} / \mathrm{sec}\). At another section \(12 \mathrm{ft}\) below the first the diameter is \(1 \mathrm{ft}\) and the pressure \(p_{2}=40\) psia.

(a) Compute the frictional losses between these two sections.

(b) Determine the direction of flow.
