{{id}} {{{paragraph}}}
I COURSE OBJECTIVES Chapter 7 7. Resistance AND Powering OF Ships 1. Define effective horsepower (EHP) conceptually and mathematically 2. State the relationship between velocity and total Resistance , and velocity and effective horsepower 3. Write an equation for total hull Resistance as a sum of viscous Resistance , wave making Resistance and correlation Resistance . Explain each of these resistive terms. 4. Draw and explain the flow of water around a moving ship showing the laminar flow region, turbulent flow region, and separated flow region 5.
RESISTANCE AND POWERING OF SHIPS . 1. Define effective horsepower (EHP) conceptually and mathematically . 2. State the relationship between velocity and total resistance, and velocity and ... It will be observed from the figure that the doubling of speed of the Navy YP from 7 to 14 knots increases the power by a factor of 10! Speed and power ...
