AI Thread Summary
To calculate the RPM of a new engine design, it's essential to know the maximum power output and the corresponding speed at which this power is achieved. The discussion highlights the importance of using an indicated diagram to correlate power and speed values. A dynamometer can be utilized to measure brake horsepower, allowing for the calculation of power using the formula torque multiplied by angular velocity. Participants shared resources and clarified the necessary variables for accurate calculations. Understanding these factors is crucial for determining the engine's RPM effectively.

I have been working on a new idea. However, i could not find out how to calculate the r.p.m of the power source. How do i do it.
 
Engineering news on Phys.org
well i'll give you an overview.
i have calculated the torque. what i want to know is how to find out the rpm of the engine. it is a new type of engine. what are the variables i need to know and stuff.
 
hello banerjeerupak
well,when u mention how much power(max power the engine can produce--)u have to mention at which speed?
so at a certain speed u can get a certain power-
and for this max power the engtine can generate---its can be monitored at a different values for the speed---in an indicated diagram of the power&speed ---
which kind of the power u talking about?
for the rated power-couldnt u see the max speed in the dashboard?and then u could calculate how much power?
for the brake hp__u could use a dynamometer_in which the speed is indicated_and torque calculated_and then (torque*angular velocity=power)
hope i could help u-
 
thank you 'Q_Goest' for the website. it was the thing that i was looking for. thanks 'machinest' for explaining how to put the problems as well as the variables in question...
 
How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...
Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'
Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
I'd like to create a thread with links to 3-D Printer resources, including printers and software package suggestions. My motivations are selfish, as I have a 3-D printed project that I'm working on, and I'd like to buy a simple printer and use low cost software to make the first prototype. There are some previous threads about 3-D printing like this: https://www.physicsforums.com/threads/are-3d-printers-easy-to-use-yet.917489/ but none that address the overall topic (unless I've missed...
