I-Calculator ye-horsepower
Linganisa amandla enjini kusuka ku-torque ne-RPM, noma ubike ijubane lokucindezela le-quarter-mile.
Iziphetho zivuselelwa uma ubhala.
Malunga nale khadi
the second mode, the engine power follows directly from torque and rotational speed: HP = torque (lb-ft) × RPM ÷ 5252. The magic number 5,252 comes from the definition of horsepower (33,000 ft-lb per minute) and the 2π radians in a revolution, and it is also the RPM at which the horsepower and torque curves always intersect on a dyno chart. The tool reports the metric equivalent too, using 1 hp = 0.7457 kW. A high-revving engine produces 300 lb-ft of torque at 5,000 RPM, which is about 213 hp. As a result, the engine produces 300 lb-ft of torque at 5,000 RPM.As a working example, HP = torque (lb-ft) × RPM ÷ 5252. As a working example, HP = torque (lb-ft) × RPM ÷ 5252. As a working example, HP = torque (lb-ft) × RPM ÷ 5252. As a working example, HP = torque (lb-ft) × RPM ÷ 5252. As a working example, HP = torque (lb-ft) × RPM ÷ 5252. As a working example, HP = torque (lb-ft) × RPM ÷ 5252. As a working example, HP = torque (lb-ft) × RPM ÷ 5252. As a working example, HP = torque (lb-ft) × RPM ÷ 5252. As a working example, HP = torque (lb-ft) × RPM ÷ 5252. As a working example, HP = torque (lb-ft) × RPM ÷ 5252. As a working example, HP = torque (lb-ft) × RPM ÷ 5252. As a working example, HP = torque (lb-ft) × RPM ÷ 5252. As a working example, HP = torque (lb-ft) × RPM
Imibuzo ebuzwa kaningi
Kungani 5252 kufomula ye horsepower?
I-horsepower icaciswa njenge-33,000 ft-lb ngomzuzu, futhi ushintsho olulodwa lususa ama-radians angama-2π. Ukuxhuma izimo eziqhubekayo kunikeza i-HP = torque × RPM ÷ 5252, okuwukuthi kungani i-horsepower ne-torque curves zihlala ziqhathaniswa ku-5252 RPM kwi-dyno chart.
Ungalinganisa kanjani amandla emoto kusuka ku-quarter mile?
Roger Huntington's formula ixhuma isivinini iphutha kanye nobunzima amandla: isivinini iphutha ≈ 234 × (hp / ubunzima) ^⅓ mph. I-calculator ishintsha isilinganiso isivinini iphutha kanye isikhathi esidlule kusuka amandla akho nobunzima, umhlahlandlela oqinile ukuthignore ukuthwala kanye aerodynamics.
Ingabe ama-watts angaba amaphi uma i-horsepower eyodwa ikhona?
I-horsepower eyodwa ye-mechanical ilingana ne-745.7 watts, ngakho-ke i-300 hp ilingana ne-224 kW. I-calculator ibonisa i-kilowatt elinganayo kanye ne-horsepower.
Kungani i-torque efanayo inikeza amandla ahlukene e-horsepower e-RPM ahlukene?
HP = torque × RPM ÷ 5252, ngakho 300 lb-ft yenza mayelana 286 hp ku 5,000 RPM kodwa kuphela 143 hp ku 2,500 RPM - isizathu ama-engine revved ukufinyelela amandla ophezulu.
Yini amandla angcono okulingana nobunzima bemilenze emibili ehamba ngokushesha?
Ukushesha kokuqhuma kulinganiselwa nge-cube root ye-horsepower nge-pound, ngakho ubunzima bubalulekile njengoba amandla. Okungaphezu kuka-0.1 hp nge-pound (350 hp, 3,500 lb imoto) kukubeka ku-110 mph ukuqhuma; ukulahlekelwa ubunzima kusiza kakhulu njengokungeza amandla.
Ingabe ngizolinganisela amandla emoto kusuka ku-trap speed yami?
Imodi yengxenye yemile iqhuba ifomu leHuntington kusuka kumandla nobunzima ukuya kukhawulo we-trap ne-ET. Ukuhamba ngenye indlela, lungisa isingeniso se-horsepower kuze kube yilapho khawulo we-trap olindelekile ufana ne-one yakho elinganiselwe - ukuthi i-horsepower iyisilinganiso esincane.
Ingabe ukulinganiselwa kwengxenye yemile efanele?
Ifomula Huntington's ukukhohlwa ukunyakaza, aerodynamics, gearing, ukuqala indlela kanye driveline ukulahleka, ngakho imoto engempela ingaba ezingu-10s eziningi sesibili off. Babhekane nabo njengendlela, hhayi umlingani we uhambo olulodwa.
