How Gauss’s Law helps in determining the Electric Field Intensity from a vector field. Calculate the total outward flux from a cylindrical surface S for the following 5 charges present inside: q1 = +3nC, q2 = -2nC, q3 = +2nC, q4 = +4nC and q5 = -1nC

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines
