Calculate the flow rate of liquids and gases using velocity, cross-sectional area, or volumetric flow. Step-by-step solutions for pipes, channels, and ducts.
Flow Rate calculator:
This Flow Rate Calculator will work out the volumetric or mass flow of liquids and gases with the use of this calculator. Type in the velocity of entry, the area of the pipes/ducts, or the density of the fluid you want to apply to calculate the flow rate, velocity, and discharge using step-by-step calculations.
slider-crank unit conversion Tool Formula:
It is a Slider-Crank Mechanism Calculator, which assists users in studying planar slider-crank linkages, which are common in engines, pumps, and piston-cylinder mechanisms. It computes crank angle (θ2), slider (x), and connecting rod angle (θ3), and linear or angular velocity at a given input angular velocity.
Users can input crank length, connecting rod length, crank angle, and optional angular velocity of the crank. The calculator applies the geometric loop-closure equation:
Formula: \( x = r cos \theta_{2} + \sqrt{I^{2} - (r sin \theta_{2})^{2}} \)
To calculate the slider position and the angle of the connecting rod. The solutions are given step-by-step so that a better understanding of the kinematics is considered. The tool works with SI units: meters ( m ) in the case of length, radians/degrees ( rad/degrees ) in the case of angles, and m/s or rad/s in the case of velocity. Other options are analysis of velocity, plotting the slides' motion, and the results, which can be printed. Perfect as a reference to mechanical engineering students, teachers, engineers, and designers of piston-crank systems.
⚡ Work & Installation Input to Output:
Input:
- Crank length (r), Connecting rod length (l)
- Crank angle θ2 (deg/rad)
- Optional crank angular velocity ω2
- Units: meters (m) for lengths, degrees/radians for angles, m/s or rad/s for velocities
Processing:
- Validate inputs (crank length < connecting rod length)
- Compute slider displacement: \( x = r cos \theta_{2} + \sqrt{I^{2} - (r sin \theta_{2})^{2}} \)
- Compute connecting rod angle: \( \theta_{3} = arcsin(\frac{\textrm{r sin}\theta_{2}}{\iota}) \)
- If ω2 provided, compute slider velocity v = r ω2 sin θ3 / sin(θ3 - θ2)
- Optional: compute angular velocity of connecting rod
Output:
- Slider position (x)
- Connecting rod angle (θ3)
- Slider velocity (v) and connecting rod angular velocity (if ω2 given)
- Step-by-step calculations
- Optional plots and printable results
Testing and Final Adjustments
Test common scenarios:
- r = 0.1 m, l = 0.4 m, θ2 = 30° → compute x and θ3
- Check slider motion for θ2 from 0° to 180°
- Validate velocities if ω2 = 10 rad/s
- Confirm step-by-step formulas and numeric results are consistent
- Edge cases: crank perpendicular or aligned with slider
- Validate unit conversions (m ↔ mm, deg ↔ rad)
- Ensure mobile/desktop UX: numeric keypad, field labels, and error messages
- Include preset examples (engine piston motion, pump mechanism)
- Optimize SEO metadata: "Slider-Crank Mechanism Calculator," "Slider Displacement," "Connecting Rod Angle," "Velocity Analysis," and schema markup
