How far could a steamboat go?

As long as steam was produced and the water in the river was deep enough it could go as far as needed.


Why does my pressure drop when your well pump turns on?

You have air getting into the water somewhere, go down and make sure every hose and fitting is tight.


What would cause the pipes to rattle whenever the hot water recirculating pump is running?

I don't even know what a recirculating pump does but when fast moving water hits a corner or elbow it has a force that can move the pipe. Most likely the pipes need a bit more tie downs. Hopefully the pipes aren't in the walls. Get someone to cut the water on and you go hunt the rattle.


Explain the effect of cavitation on propeller blades?

The BLADES ON THE IMPELLER GATHER BUBBLES AND POP. THE POP OF THE BUBBLES BREAK AND INDENT THE IMPELLER AND GUIDEVANE THAT HELPS THE WATER OR FLUID GO FROM THE MIDDLE OF THE IMPELLER TO THE LEADING EDGE OF THE IMPELLER. THE SOUND OF CAVITATION IS LIKE PUMPING GRAVEL THROUGH THE VOLUTE OR CASE. IF THE PUMP IS CAVITATING YOU CAN SLOWING CLOSE A BALL VALVE ON THE DISCHARGE SIDE OF THE PUMP ON A CENTRIFUGAL PUMP AND THE GRAVEL NOISE WILL GO AWAY AND YOU KNOW THE PUMP IS CAVITATING. CAVATION WILL DESTROY AN IMPELLER VERY FAST BY IMPLODING BUBBLES ON THE METAL OR PLASTIC UNTILL THE PUMP WILL NOT RUN.


Boiler works but no hot water?

Sounds like you have a bad zone valve or zone pump. There is either a pump, and the zones in the house have zone valves, or each zone has it own pump. Zone valves go bad all the time, you can just replace the motor on it instead of sweating the new valve in. The box that is on top of the valve.
