Problem
In a certain siphon, viscous effects cause the water to lose 5 % of its mechanical energy between the inlet and the outlet. Compared with the ideal (no-loss) prediction for exit speed, the actual exit speed is
(a) about 10% lower
(b) approximately 2.5% lower
(c) 5% lower
(d) unchanged because energy loss does not affect speed
