Titanic's Proposed Coal Consumption | Page 2 ...

Jul 28, 2001 · Regarding similar coal consumption figures, when researching about Aquitania for a possible volume on her, the contract stated she was not to burn more than 825 tons of coal in 24 hours while running at 23 knots. During the same period, at 24 knots the ship was not to burn more than 950 tons of coal.

Fuel Consumption by Containership Size and Speed | The ...

Fuel consumption by a containership is mostly a function of ship size and cruising speed, which follows an exponential function above 14 knots. For instance, while a containership of around 8,000 TEU would consume about 225 tons of bunker fuel per day at 24 knots. At 21 knots this consumption drops to about 150 tons per day, a 33% decline.

Hard Acceleration / Energy Consumption | Tesla

Oct 12, 2013 · Imagine the following two scenarios: 1. Accelerate HARD to 60 mph, drive for a short while and then decelerate to a stop for an average speed of (say) 40 mph. 2. Accelerate very gently to slightly above 60 mph such that the average speed for the entire run is also 40 mph, then decelerate to a stop as in scenario 1. So, apart from the (slight?) difference due to additional tire distortion in 1 ...

Table of energy consumption vs. speed | Tesla

Nov 22, 2014 · I haven't seen a simple formula for Wh/mile vs. speed, I decided to interpolate from a published graph and do some simple curve fitting. From 45 to 80 MPH, I found that Wh/mile = MPH^2 / 30 + MPH * 5/6 + 120 fits the curve well: MPH Curve Calulated 45 225 225 50 245 245 55 270 266.6666667 60 290 290 65 320 315 70 340 341.6666667 75 370 370 80 400 400 Does anyone have .

How is Electricity Measured? | Union of Concerned Scientists

Kilowatt-hours are what show up on your electricity bill, describing how much electricity you have used. One kilowatt (kW) equals 1,000 watts, and one kilowatt-hour (kWh) is one hour of using electricity at a rate of 1,000 watts. New, energy-efficient refrigerators use about 300-400 kilowatt-hours per year.
