## Overview

Q5-1 | A rectangular sluice gate is 6 ft wide and 9 ft high. It is immersed vertically in water with the 6-ft edges horizontal. Water stands on one side of the gate at a depth level with its upper edge and on the other side at a depth of 4.5 ft below the upper edge. The gate is hinged at the top edge and is held in equilibrium by a horizontal force applied at its lower edge. Calculate this force. | |

Q5-2 | A flashboard 2.5 ft high mounted above the crest of a dam is supported by a standard (Schedule 40) 2-in. pipe of steel placed on 8-ft centers. The pipes fail and the flashboard goes down at a head on the crest of the dam amounting to 4.15 ft of water. ( | |

Q5-3 | A cylindrical log is 1 ft in diameter and 20 ft long. What weight of iron must be tied to one end of the log to keep it floating in an upright position in seawater with 18 ft of the log submerged. Specific gravity of log is 0.7, of iron 7.9, and of sea water 1.03. | |
