My washing machine does 1500rpm, what speed would that be in mph?

Answer 1

first you should calculate the speed in hours:
1500/60=25rph
then it's up to the radius of the internal part in you washing machine;
if u know the radius, the speed will be:
25*radius.
if the radius u've got is in miles, you should be finished, else, if you get the radius in meters you should multiply the the resulting value by 0.000621371 to convert it from meter per hour to a mile per hour... that's all.

Answer 2

depends on the diameter, and where on the circle youre measuring. 1500rpm just means that the thing is turning around at 1500 revolutions per minute. If you were to draw a spot (lets call it spot A) close to the axis, and another spot B close to the edge of the turning part, then spot B has to cover more distance than spot A to complete 1 revolution.

Spot B will thus be moving faster in terms of MPH than spot A, but it's impossible to work out the exact speed without knowing the diameter.

Answer 3

Objects in your washing machine travel at different speeds, depending on where they are located. Items located at the center of the spin travel more slowly than items at the edge of the basket. This is due to the fact that speed is the distance travelled over time:

V = d/t

One rotation in completed in the same amount of time, no matter where in the basket the clothing is. However, you can see that clothing at the center travels a shorter distance around in one rotation, and therefore has a slower speed.

To adequately answer this question, you'd have to use calculus, or know the exact distance the item is from the center of the spin. You can calculate the roatations per hour, but not miles per hour.

Perhaps you need to clarify your question?

Answer 4

You basically need to get the size of the drum, figure how many revolutions it would take for it to go a mile and then divide the 1500RPM by that figure, then times by 60 (for an hour) to get your MPH.

Answer 5

The speed depends on the size of the washing machine. The larger the diameter of the tub in the washer, the more distance the edge of the tub travels at a given RPM.

Answer 6

This depends on the diameter of the drum. Since you are converting in to mph which is measurement of linear distance travelled, you are likening it to a wheel. Supose D is the outer dia of the drum in miles, it's spped in mph will be :
pi*D*1500*60

Answer 7

Actually, RPM and MPH have little to do with eachother. RPM, is just how fast the motor is spinning at revolutions per minute. If you hooked up the motor to a a set of gears, at different rations, you could get 10 MPH, or if you did it with smaller gears, and different ratios, you could get 300+

Answer 8

lets assume that the actual drum during a spin cycle does 1500rpm.

lets also assume that the radius of your drum is an irrational constant.....let say ......R.

now choose a point (say r) so that it is r cm away from the centre of the drum and that:-
0 ≤ r ≤ R.

now the distance travelled during one revolution of the drum at this point is :-
2*π*r cm

and during 1500 revolutions (i.e.1500rpm), gives a total distance of :-
2*π*r*1500 = 3000*π*r cm per minute.

convert this into cm per hour by multiplying by 60 :-

3000*π*r*60 = 180000*π*r cm per hour

convert this into Km per hour by dividing by 100000 :-

(180000*π*r)/100000 = 1.8*π*r Km per hour

now convert this into mph by multiplying by 5/8 (or dividing by 1.6) :-
1.8*π*r *(5/8) = 1.125*π*r mph.

This gives the speed for every point of your drum. since during a spin cycle, all clothes are thrown towards the outer edge of the drum (due to normal force), the majority of your clothes will be at almost R distance from the centre of the drum. therefore you can assume :-
r ≈ R

and so your clothes will travel at approximately :-

1.125*π*R

(where R is the radius of the drum).

Answer 9

I have an LG steamwasher that is the biggest in front loaders and I would guess if it were a tire on a car it would be like 60-80mpg just in what it looks like.. It is scary how fast they spin! It sounds like being on a plane reving the jets.

Answer 10

it depends....you cant really compare it to the speed of a car because it depends on the torque for instance in a car it would be roughly 40mph....now it could be the same if the torque is the same but we're talking about a car vs an appliance ...t= FxR where F is the force vector and r is the vector from the axis of rotation to the point on which the force is acting...its like in our cars vs race cars (nascar)....the tach on my car will read 2500+/- rpm at 60mph but will read 6400 +/- at 100mph on a racecar...see the difference?
