Mixer Grinder
QUESTION: Dear Prof Scott

Will it be feasible to design and manufacture a Mixer Grinder Electrical Appliance with rechargeable batteries as the source of power input and DC Motors part of the Appliance replacing the conventional 230 V Ac, 50 Hz primary input source ?.

If this is possible will this have a edge over the conventional Mixer Grinder electrical appliance in terms of price, safety, appliance operations, portability, Power consumption etc to the consumer ?.

Thanks & Regards,

ANSWER: I don't have time to look up all the documents sent, but I can say that almost anything can be done with a battery.  As an example, all cars use batteries to start.  The reason cars don't run on batteries is that it takes too much energy to keep them going.  That is why they were made using gasoline.  When they were first designed, this was a cheap way to keep them going.  As there are getting to be so many in the world, some people are looking into how to design them to work off a cheaper source.  I haven't heard much detail about it yet, but know that they have found another way to make them run.

When I was a kid, all they had were size A, B, C, and D batteries.  Now they have AA batteries, AAA batteries, watch batteries, calculator batteries, and who knows what else.  I'm sure someday they might develop one to run equipment that does a whole lot more work.

QUESTION: Dear Prof Scott

Thank you.

Attached image for the design changes.

We have to calculate the Input Batteries Voltage (Volts) and
Current (Amperes) required for driving the D.C Motor and
calculating the Output Power (Watts).

Example
-------

Portable Mixer Grinder can be carried in a Car for making fresh watermelon,
apple, orange juices etc.

Do you have any suggestions , inputs regarding the design ?.

Thanks & Regards,

I suppose they could probably make a machine to make juice in your car.
It might be easier, however, to just throw in several cans of juice with pull-tops.

By the way, a period is not suppose to be after a question mark.
Do you know what I mean?

#### Scott A Wilson

##### Expertise

I can answer any question in general math, arithetic, discret math, algebra, box problems, geometry, filling a tank with water, trigonometry, pre-calculus, linear algebra, complex mathematics, probability, statistics, and most of anything else that relates to math. I can also say that I broke 5 minutes for a mile, which is over 12 mph, but is that relevant?

##### Experience

Experience in the area; I have tutored people in the above areas of mathematics for over two years in AllExperts.com. I have tutored people here and there in mathematics since before I received a BS degree back in 1984. In just two more years, I received an MS degree as well, but more on that later. I tutored at OSU in the math center for all six years I was there. Most students offering assistance were juniors, seniors, or graduate students. I was allowed to tutor as a freshman. I tutored at Mathnasium for well over a year. I worked at The Boeing Company for over 5 years. I received an MS degreee in Mathematics from Oregon State Univeristy. The classes I took were over 100 hours of upper division credits in mathematical courses such as calculus, statistics, probabilty, linear algrebra, powers, linear regression, matrices, and more. I graduated with honors in both my BS and MS degrees. Past/Present Clients: College Students at Oregon State University, various math people since college, over 7,500 people on the PC from the US and rest the world.

Publications
My master's paper was published in the OSU journal. The subject of it was Numerical Analysis used in shock waves and rarefaction fans. It dealt with discontinuities that arose over time. They were solved using the Leap Frog method. That method was used and improvements of it were shown. The improvements were by Enquist-Osher, Godunov, and Lax-Wendroff.

Education/Credentials
Master of Science at OSU with high honors in mathematics. Bachelor of Science at OSU with high honors in mathematical sciences. This degree involved mathematics, statistics, and computer science. I also took sophmore level physics and chemistry while I was attending college. On the side I took raquetball, but that's still not relevant.

Awards and Honors
I earned high honors in both my BS degree and MS degree from Oregon State. I was in near the top in most of my classes. In several classes in mathematics, I was first. In a class of over 100 students, I was always one of the first ones to complete the test. I graduated with well over 50 credits in upper division mathematics.

Past/Present Clients
My clients have been students at OSU, people who live nearby, friends with math questions, and several people every day on the PC. I would guess that you are probably going to be one more.
