Problem 18.3: aluminum wire, having a diameter of 0.794 mm, is immersed in an oil bath that is at 25°c. aluminum wire of this size has an electrical resistance of 0.0572w/m. for conditions where an electric current of 100 a is flowing through the wire and the surface coefficient between the wire and oil bath is 550 w/m2.k, determine the steady-state temperature of the wire.

tube or goog with be a great resource to with that question

cant without the picture! ?

answer a fan shaped mass of sediment deposited at the base of a mountain front do to an abrupt change in stream gradient;

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
