    Power Torque
AI Thread Summary
To calculate torque and power for diabolo rollers, one must consider the maximum weight of the pipe, which is 22 tons, and the desired RPM of 30. The torque can be determined using the formula Torque = Force x Radius, where Force is derived from the weight of the pipe. Additionally, power can be calculated with the formula Power = Torque x RPM, converting units as necessary for consistency. The discussion also references a similar thread that provides further insights into the calculations required for roller systems. Accurate calculations are essential for selecting the appropriate hydromotor for the application.

Hi everybody
I'm designing a diabolo roller station for centeralizing of pipe consist of 2 rubber coated diabolo.the max weight of pipe is 22 tons and rpm is 30.
i need to calculate torque for selecting of hydromotor.
i appreciate if help me.

Thread 'Bubble formation in 4 mm gap vessel'

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...

Thread 'Find 3D Printer & Software Resources for Prototype Creation'

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...
