Calculate the emf of a cell operating
Calculate the emf of a cell operating with the followingreaction at 25oC, in which [MnO4-]= 0.010 M, [Br-] = 0.010 M, [Mn2+] = 0.15 M,and [H+] = 1.0 M.2MnO4- (aq) + 10Br-(aq) +16H+(aq) → 2Mn2+(aq) +5Br2(l) + 8H20 .

Estimate the heat flux through the wall for following conditions: heat transfer coefficients in the inside and outside as 10 and 65 W/m2 K respectively; inside and outside temperatures are 20oC and 0oC respectively.
Find the value of heat transfer coefficient that will ensure that the surface temperature will not exceed 45oC. What is the heat flux through the insulation?
If the friction force on the metal foil surface is 0.3 N, determine the surface temperature of the metal foil. Evaluate the fluid properties at 100 deg C.
It is known that atmospheric air flows parallel to the flat surface (U∞ = 25 m/s, T∞ =20 C), and that the flow induces a drag force of 1N. What is the electrical power needed?
Ball A is dropped from the top of a building of height h at the same instant that ball B is thrown vertically upward from the ground. When the balls collide, they are moving in opposite directions, and the speed of A is twice the speed of B. At wh
