If you could then perform the same test in a water tunnel, what would the speed of water in the tunnel be? density of water = 1000 kg/m^3, density of air = 1 2 kg/m^3, dynamic viscosity of water = 0 001 pas and dynamic viscosity of air = 1 983 10^-5 pas

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.
