Question

A ship 150 m long moves in fresh water at 15°C at 36 km/h. A 1:100 model of
this ship is to be tested in a towing basin containing a liquid of specific gravity
0.90. What viscosity must this liquid have for both Reynolds and Froude model
laws to be satisfied ? At what speed must the model be towed ? If 117.7 watts is
required to tow the model at this speed, what power is required by the ship ?
Dynamic viscosity of water at 15°C is 1.13 × 10–3 N.s/m2

Answer 2

Step-by-step explanation:

A ship 150 m long moves in fresh water at 15°C at 36 km/h. A 1:100 model of

this ship is to be tested in a towing basin containing a liquid of specific gravity

0.90. What viscosity must this liquid have for both Reynolds and Froude model

laws to be satisfied ? At what speed must the model be towed ? If 117.7 watts is

required to tow the model at this speed, what power is required by the ship ?

Dynamic viscosity of water at 15°C is 1.13 × 10–3 N.s/m2
