Determine the correct diameter and pitch of a propeller for any given vessel and engine.

Boat power usage calculator. To use the calculator input four of the five variables. Starting with the boats LWL from the graph you determine the boats C-value. Subtract AES line from Gross consumption to find out how much energy must be made up using other sources.

From where we calculate the result as. Pitch inches RPM max revmin 1 min reductionRatio 1215223 speed inchesmin 1 min. Where the value of speed is in knots.

With knowledge of a boats fuel economy-how much fuel the boat burns per mile or nautical mile of travel-boaters can estimate the range they can safely expect to run. These values are based on a 12 V DC nominal system. To answer this question OuterVision PSU Calculator analyzes dozens of power supplies per each certification category compares their efficiency unit price computer power consumption overall PC energy cost and payback period.

Heres our at anchor list as a starting point note that you need to know amps per hour AND an estimate of how many hours you use the item to calculate daily amp usage. To apply these formulas to your boat plug in its horsepower rating and multiply it by the specific fuel consumption average then divide the product by the fuel specific weight Formula To Estimate Maximum Engine Fuel Consumption Gallon Per Hour GPH specific fuel consumption x HPFuel Specific Weight Constants Gas Diesel. The chart below shows examples of energy consumption of various equipment.

Gas and diesel prices are updated in real time but the numbers represent national averages so your local fuel costs could vary. What power supply do I need. LED Anchor Light 25hour X 10 hours 25 ampsnight.

If an appliance drawing 5A was to run for 1 hour its consumption would amount to 5Ah. So amp-hours are simply the average amperage drawn multiplied by the time in hours. Be careful to express the displacements in.
