AI Thread Summary
Higher horsepower generally contributes to a vehicle's potential for a higher top speed, assuming all other factors are equal. However, gearing plays a crucial role; increasing horsepower without adjusting the gearing may not yield a higher top speed. The relationship between horsepower and road speed is influenced by factors such as aerodynamics, weight, and tire performance. Ultimately, while horsepower is a significant factor, it must be optimized with appropriate gearing to achieve maximum speed. Therefore, both horsepower and gearing must be considered to determine a vehicle's top speed effectively.

Assuming everything else is equal between two cars, would the car with the higher horsepower have higher top speed and vice versa?

What dictates a vehicles road speed?
 
if you took one car and increased the engine horsepower but at the same engine rpm, you would need to lengthen the gearing to suit the higher potential top speed.

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
