The numerical analysis which studied laminar flow and viscous flow in rectangular tube which rotates in the circumference of shaft of the tube and perpendicular shaft was carried out. Upwind difference scheme of the third accuracy was used for the advective term. The uniform thermal flux from tube wall in the fluid which flows is applied the inside of the tube. Flow field and temperature field were obtained to the high Reynolds number. The equation of the friction coefficient ratio considering aspect ratio and rotational frequency was clarified. The equation of the Nusselt number ratio was also similarly clarified considering aspect ratio and rotational frequency.
