The amount of gallons of water that will flow through a 1/2 inch hose Bibb per hour with a source pressure of 70 psi is around 60. To figure the exact amount, turn the water on full force and time how long it takes to fill a one gallon bucket. To figure gallons per minute, divide that by 60. Take that number and multiply by 60 to find gallons per hour.
