A 60-Hz 3-phase induction motor is required to drive a load at approximately 850 rpm. How many poles should the motor have
Anastaziya [24]

Answer:

8 poles

Explanation:

Given

Frequency, f = 60Hz

Speed, n_s = 850rpm

Required

Calculate the number of poles the motor should have?

To solve this question, we make use of synchronous angular velocity  formula

n_s = \frac{120f}{P}

Where

P = Number\ of\ Poles

Substitute values for n_s and f in n_s = \frac{120f}{P}

850 = \frac{120 * 60}{P}

850 = \frac{7200}{P}

Multiply both sides by P

P * 850 = \frac{7200}{P} * P

P * 850 = 7200

Divide both sides by 850

\frac{P * 850}{850} = \frac{7200}{850}

P = \frac{7200}{850}

P = 8.47058823529

However, the number of poles must be an integer.

So:

P = 8

If coolant is mixed 50-50 with water, what is the freezing point?
sashaice [31]

Answer:

-35 degrees F

When mixed in equal parts with water (50/50), antifreeze lowers the freezing point to -35 degrees F and raises the boiling temperature to 223 degrees F. Antifreeze also includes corrosion inhibitors to protect the engine and cooling system against rust and corrosion.

yKpoI14uk [10]

Answer:

The correct approach will be "Polymer".

Explanation:

  • A polymer, because it has a very broad molecular structure, seems to be a class or kind of organic solid. It is indeed a material consisting of long sequences, or monomers, of simplified components.
  • The existence of a large number of monomers which have been mentioned several times seems to be the principal design characteristic of polymeric materials.
