How to calculate the speed of a cross flow water turbine?

Click For Summary
SUMMARY

The discussion centers on calculating the speed of a cross flow water turbine, emphasizing the necessity of specific parameters such as configuration, flow, head, and load for accurate computation. Participants highlight that a comprehensive understanding of these factors is crucial, as the formula for speed calculation cannot be provided without detailed information. The conversation suggests that students should demonstrate their attempts at solving the problem before seeking assistance, reinforcing the importance of foundational knowledge in engineering principles.

PREREQUISITES
  • Understanding of cross flow turbine mechanics
  • Knowledge of fluid dynamics principles
  • Familiarity with torque and its role in rotational systems
  • Basic engineering problem-solving skills
NEXT STEPS
  • Research the specific formulas for calculating turbine speed based on flow and head parameters
  • Study the principles of torque equilibrium in rotating machinery
  • Explore case studies on cross flow turbine design and performance
  • Learn about the impact of load variations on turbine efficiency
USEFUL FOR

Mechanical engineers, students in machine design courses, and anyone involved in the design and analysis of water turbines will benefit from this discussion.

You would need a lot more information to do that . Configuration, flow, head, load...more

You need more help than an answer from an internet forum. Talk to your teacher.

Is this what you mean?

Yes, that's what I mean.
 
What if I have all of the parameters to compute the speed of the cross flow turbine, what formula should I use?

In the steady state, the sum of all torques is zero.

This sounds like homework and it should have been posted in the homework forum. We are not allowed to just spoon feed answers to students. You must show your attempt at a solution first.

This isn't a 1+1=2 question. You need to give a complete description of what you have and need in order for it to be answerable.
