Torque due to magnetic force on a loop
1 votes

Using small sections from any loop we get: $\tau = I \Delta r \times(\Delta l \times B) $ Now use rule for triple cross product: $A \times B \times C = B(A.C) - C(A.B)$ //back cap Now it's clear that ...

In steam turbine plant like Rankine cycle(for example): The fluid is incompressible as in continuity equation, so the system is isentropic which implies that Vdp integral is used and dV is ZERO. I ...
