How is SFC calculated?

How is SFC calculated?

The units of this efficiency factor are mass per time divided by force (in English units, pounds mass per hour per pound; in metric units, kilograms per hour per Newton).

What is a good MPG?

A normal petrol engine just has trusty old gasoline and no fancy electric motors. While the Prius gets around 60 mpg, something that gets at least 30 mpg might classify as good. Here are some cars that get at least 30 mpg from the last few years: 2014 BMW 328i (35 mpg highway, $21,000)

What is MPG math?

The math is simple arithmetic. Divide the total number of miles driven (10,000) by the miles per gallon to get the total gallons used to drive that distance. A much more direct way to measure fuel consumption is an estimate of the amount of gas required to travel a given distance.

How is Bmep calculated?

BMEP = (Torque x 75.4) / (Displacement x PPR) It is also clear that because the equation includes PPR ( Power Pulses per Revolution ), it applies to engines with any number of cylinders by using the total displacement, total brake torque, and correct PPR.

Is it desirable to have a high or low SFC?

SFC is defined by fuel flow rate per unit power output. It measure how efficiently an engine is using the fuel supplied to produce work. Low values of SFC are -obviously desirable. In figure 8 shows SFC of WPPO and biodiesel.

Which car gives the best mileage?

What’s the average MPG for a car?

24.9 mpgUS
In more recent studies, the average fuel economy for new passenger car in the United States improved from 17 mpg (13.8 L/100 km) in 1978 to more than 22 mpg (10.7 L/100 km) in 1982. The average fuel economy for new 2017 model year cars, light trucks and SUVs in the United States was 24.9 mpgUS (9.4 L/100 km).

What is the difference between miles and mileage?

In context|informal|lang=en terms the difference between mileage and mile. is that mileage is (informal) something worth taking into consideration while mile is (informal) one mile per hour, as a measure of speed.

How to calculate the flow rate of water?

This calculator may also be used to determine the appropriate pipe diameter required to achieve a desired velocity and flow rate. The following formula is used by this calculator to populate the value for the flow rate, pipe diameter or water velocity, whichever is unknown: V = 0.408 × Q/D2.

How is the velocity of water measured in a stream?

The current meter is used to measure water velocity at predetermined points (subsections) along a marked line, suspended cableway, or bridge across a river or stream. The depth of the water is also measured at each point.

How often is discharge measured at a streamgage?

The USGS makes discharge measurements at most streamgages every 6 to 8 weeks, ensuring that the range of stage and flows at the streamgage are measured regularly. Special effort is made to measure extremely high and low stages and flows because these measurements occur less frequently.

How is the average interval between low and high water determined?

It is obtained by subtracting the mean of the lower low waters from the mean of all the low waters. The average interval (in hours) between the moon’s transit over the Greenwich meridian and the following high water at a location.
