AI Thread Summary
To calculate the reaction force from a fluid, the key variables are nozzle size, fluid density, and pressure. The thrust can be derived from the momentum equation, which relates the mass flow rate and velocity of the fluid exiting the nozzle. For a round hole with a diameter of 2mm and water ejected at 100Bar, the area is approximately 3.1416x10e-6 m^2. Understanding these principles allows for accurate calculations of the reaction force generated by the fluid. Utilizing the provided NASA link can offer additional foundational knowledge on the topic.

Does anyone know how to figure out the reaction force from a fluid if the known variables are nozzle size fluid density and pressure?
Say as an example we are ejecting water at 100Bar from a round hole 2mm diameter (3.1416x10e-6 m^2)
Thanks in advance for any formulas :)

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Calculation of Tensile Forces in Piston-Type Water-Lifting Devices at Elevated Locations'

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
