Do Steam-rockets follow the same calculations of turbines

In summary, the exhaust velocity of water in a steam rocket is determined by the temperature and pressure of the steam. The same thermodynamics principles used for turbines can be applied to calculate the distance the rocket can travel. However, factors such as the design of the turbine, temperature and pressure of the steam, and other external factors must be considered for accurate calculations.

Hello, I'm working on a small steam rocket and I want to calculate how far up it can get by calculating the exhaust velocity of water after it's heated. I saw a similar exercise on my thermodynamics book but for turbines. Can I use the same calculations for the rocket.

Yes, you can use the same calculations for a rocket. The exhaust velocity of water is determined by the temperature and pressure of the steam. The higher the temperature and pressure, the higher the exhaust velocity. In order to calculate the distance travelled by your rocket, you will need to know the amount of energy available from the steam and the mass of the rocket.

Hi there! That's a great question. The basic principles of thermodynamics can definitely be applied to your steam rocket project. However, there are a few factors that you'll need to consider in order to accurately calculate the exhaust velocity and distance your rocket can reach.

First, the type of turbine you mentioned in your book may not be the same as the one in your rocket. The design and construction of the turbine can affect the efficiency and output of the steam, so make sure you do some research to find the appropriate equations for your specific setup.

Second, the temperature and pressure of the steam will also play a big role in determining the exhaust velocity. You'll need to measure and control these variables carefully in order to get an accurate calculation.

Lastly, keep in mind that there are other factors that can affect the performance of your rocket, such as air resistance and the weight of the rocket itself. These may not be accounted for in the thermodynamics equations, so it's important to do some additional calculations or experiments to get a better estimate of the rocket's potential.

Good luck with your project! Feel free to ask any further questions.
 

1. Do steam rockets use the same principles as turbines?

Yes, steam rockets and turbines both rely on the principle of Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. In both cases, hot steam is forced through a nozzle, creating a high-pressure, high-velocity jet that propels the rocket or turbine blades.

2. How does the efficiency of a steam rocket compare to that of a turbine?

The efficiency of a steam rocket is generally lower than that of a turbine. This is because a significant amount of energy in a steam rocket is lost through the exhaust, while turbines are designed to capture and use as much of the steam's energy as possible.

3. Are the calculations for steam rockets more complex than those for turbines?

In general, the calculations for steam rockets are more complex than those for turbines. This is because steam rockets not only have to account for the thrust generated by the steam jet, but also the weight and aerodynamics of the rocket itself. Turbines, on the other hand, only need to consider the forces acting on the blades.

4. Can steam rockets be used for space travel?

While steam rockets have been used successfully for atmospheric flight, they are not powerful enough to overcome Earth's gravity and reach space. However, there is ongoing research into the use of steam-powered spacecraft for potential missions to other planets.

5. What are some potential drawbacks of using steam rockets over other propulsion methods?

One major drawback of steam rockets is their low specific impulse, which is a measure of how efficiently a rocket uses its fuel. This means that steam rockets require a large amount of fuel to generate enough thrust for a given amount of time, making them less efficient than other propulsion methods such as chemical rockets or ion thrusters.
