HELP ME if you know ANYTHINGG at all about physics!!!!!?

Question

1) what is the relation of a horsepower to a watt?

2) how is a BTU reated to the joule?


no, this is NOT my homework...i just need the answers cuz i have a test tomorrow please help me!!

thanks

Answer 1

1 Horsepower is defined as 745.7 watts

So for example a 1500 Watt motor (if 100% efficient) would produce approximately 2 HP

1 BTU = 1055 joules 1.055 Kj ***






*** This figure DOES vary very slightly depending on the temp involved. For more information, please go here http://www.simetric.co.uk/sibtu.htm

Answer 2

1 horsepower = 745.699872 watts
1 btu = 1 055.05585 joules

for a further answer, BTU and Joules are units of energy whereas horsepower and watts are units of power, which describe the amount of energy over a specific period of time. For instance if you run a mile, it takes so much total energy to run taht mile, however, the amount of power is the energy you are using in a sec...

Answer 3

1 watts = 1.341 * 10^-3 hp
1 J = 9.486 * 10 ^-4 BTU

1 Watt = 1 Joule/second = 9.486 * 10 ^-4 BTU/second


Good luck for your test tomorrow!

Answer 4

1 horsepower = 745.6999 watts you can take it 746 watts and by horsepower i mean mechanical hp

i dont remember the btu to joule thing cuz its energy uniy and i'm more into power

Answer 5

Horsepower to watt, multiply by 746

BTU to Joule, multiply by 1055
