A three-blade propeller of a diameter of 1.5 m has a rotational speed is 60 Hz, the activity factor AF is 200 and its static torque coefficient is 0.05. The propeller's integrated lift coefficient is 0.3.

Please answer number 6. with complete solutions and box the final answer.

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

The attached answer was provided for the attached question. The equation uses the given temperature in celcius and the answer is also given in celcius. The temperature was used in the equation without converting from F and the answer was supposed to be in F. I am worried that even if I converted the answer to celcius that it would be correct because temperature was used in the equation using the incorrect unit.

can you provide an answer easie to read. the answer is put into sentences like fcv=mgcos 6

Hi please help with this question thank you I just can't seem to work it out even with the given formulas. Thanks! also, I have tried these but they seem to be incorrect, or maybe parts of the calculation may be incorrect since when I submit these all together and I can't really work out where I am going wrong: sigma 1 = 73.31 MPa theta 1 = 56.87 degrees sigma 2 = 18.68 MPa theta 2 = 146.875 degrees Tmax in plane = 27.315 MPa theta s = 101.87 degrees

Please ANSWER ALL of the given questions.    I will rate you with “UPVOTE/LIKE” if you answer every question.   I will rate you with “DOWNVOTE/DISLIKE”, if you don’t answer every question.   THANK YOU.
