All major harbors are equipped with fire boats for extinguishing ship fires. a 3-in. diameter hose is attached to the discharge of a 15-hp pump on such a boat. the nozzle attached to the end of the hose has a diameter of 1 in. if the nozzle discharge is held 10 ft above the surface of the water, determine (a) the volume flow rate through the nozzle, (b) the maximum height to which the water will rise, and (c) the force on the boat if the water jet is directed horizontally over the stern.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
