10.25 Application: The MHD Generator. A small magnetohydrodynamic (MHD) generator is proposed as part of the
exhaust system of a jet engine. The MHD channel is 200 mm by 200 mm in cross section and is 1 m long. A magnetic
field of 1 T is generated between two surfaces as shown in Figure 10.56. The exhaust moves at 200 m/s and is seeded
to produce a conductivity of 50 S/m in the channel. Calculate:
