Anewly designed bulk carrier 852 ft long displaces 100,000 tons at de draft. resistance tests have shown that the effective power, includ- sign ing air and appendage allowances, is 12,860 horsepower at the design speed of 16.5 knots. propulsion factors measured in self-propelled model tests are: wake fraction 0.325 thrust deduction fraction-0.178 relative rotative efficiency 1.025 the propeller test revealed that at its design point the propeller's open- water efficiency is 0.685. shaft transmission efficiency is estimated at 0.990, and a service power allowance of 20 percent has been chosen. from the data given, calculate this ship's propulsive efficiency, trial shaft horsepower, and service shaft horsepower.

tube or goog will be great resources to find the answer to the question that you're asking

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27
