2. Given a frictionless flow of water at 125.6 ft³/s in a long, horizontal, conical pipe, of diameter 2 ft at one end and 6ft at the other. The pressure head t the smaller end is 18 ft of water. Find the velocities at the two ends and the pressure head at the larger end. 3. In figure, gate AB is 4 m wide and opens to let fresh water out when the ocean tide is falling. The hinge at A is 3 m above the freshwater surface. At what ocean depth h will the gate open? Neglect the gate weight. 12 m ☑ Stop A h Tide Range Sea water = 1.025 4. A fire hose should deliver at least 1200 lpm of fluid. If the nozzle has a diameter of 30mm, what is is the velocity of the issuing jet in cm/min? 5. is practically independent from pressure and depends on temperature only.
