disc of diameter

A disc of diameter D immersed in a fluid of density e and viscosity µ has a constant rotational speed ω. The power required to drive the disc is P. Show that P = eω3D5φ(eωD2/µ). A disc 225 mm diameter rotating at 144.5 rad ·s−1 (23 rev/s) in water requires a driving torque of 1.1 N · m. Calculate the corresponding speed and the torque required to drive a similar disc 675 mm diameter rotating in air. (Dynamic viscosities: air 1.86 × 10−5 Pa ·s; water 1.01 × 10−3 Pa ·s. Densities: air 1.20 kg · m−3; water 1000 kg · m−3.)
