Toy poodles can run about 5-10 mph.Medium poodles can run about 15-20 mph.Large poodles can run up to about 20-35 mph.Minor edit?ow my female border collie who is the same age and a little smaller can out run her no problem. I have yet to clock her but i am confident it will be around 30 or 35 mph. my poodle is also not nearly as agile as my border collie, though.
Valve Closure and Opening. One of the primary causes of water hammer is the abrupt closure of a valve. At the end of the branch is a valve. The black arrows show the flow direction in the primary and branch lines, and the blue arrow is the length of the branch line.
Water hammer happens when you turn OFF a water flow suddenly (like a dishwasher, a clothes washer, a toilet or even closing a hand faucet suddenly. Shutting off the flow suddenly sends a pressure or shock wave down the water line through the water shocking the pipes and creating the 'hammer' noise. These shock waves travel faster than the speed of sound and can exert very great instantaneous pressures.
