Summary
A novel Cross Floating Valve (CFV) was designed and simulated for pressure calibration systems. This new valve significantly reduces calibration time by approximately 30%, enhancing efficiency in pressure balance (PB) testing.
Area of Science:
- Mechanical Engineering
- Metrology
- Materials Science
Background:
- Pressure balances (PBs) are crucial for calibration, but the process can be time-consuming.
- Existing calibration methods lack efficiency, necessitating innovative solutions.
- The Cross Floating Valve (CFV) is a key component in pressure calibration systems.
Purpose of the Study:
- To design, simulate, and develop an improved Cross Floating Valve (CFV).
- To enhance the ease and time efficiency of pressure calibration processes using PBs.
- To evaluate the performance and impact of the CFV on calibration duration.
Main Methods:
- Material selection and component modeling for CFV design.
- Finite element analysis (FEA) using ANSYS to simulate stress, strain, and deformation.
- Fabrication and performance testing of the CFV with different pressure balances.
Main Results:
- AISI17-4PH and SS440C were selected for piston fabrication based on safety factors and cost.
- Simulations identified SS304 and SS316 as unsuitable due to low safety factors.
- CFV implementation reduced calibration time by an average of 30%.
Conclusions:
- The developed CFV is effective in simplifying and accelerating pressure calibration.
- Material selection and simulation are critical for robust CFV design.
- The CFV offers a significant improvement in calibration efficiency for pressure balance systems.

When liquid flows along an open channel at high velocity, the flow can become unstable, and slight disturbances can cause the liquid upper surface to transition abruptly to a higher level (Fig. 1a). This sharp increase in the liquid level is called a hydraulic jump. The increase in the liquid level causes a reduction in the average flow velocity....

To analyze a hydraulic jump in a rectangular channel with a flow speed of 6 meters per second, follow these steps:Calculate Effective Upstream Velocity:When the downstream gate closes, a hydraulic jump forms, traveling upstream at 2 meters per second. This wave speed combines with the initial channel flow velocity, creating an effective upstream velocity.Identify Flow Velocities Before and After the Hydraulic Jump:Upstream of the hydraulic jump, the effective flow velocity includes both the...

The objective of this experiment is to demonstrate the phenomenon of stability of floating vessels - the ability to self-right when rolled over to the side by some external force. Careful design of hull shapes and internal mass distribution enables seagoing vessels to be stable with low drafts (submerged depth of hull), improving vessel...

A hydraulic jump is a sudden rise in fluid depth in open channels, occurring when high-velocity (supercritical) flow transitions to low-velocity (subcritical) flow. This phenomenon requires an upstream Froude number greater than 1, as flows with Fr1<1 remain subcritical, making a hydraulic jump impossible due to the need for negative head loss, which violates thermodynamic principles.The characteristics of a hydraulic jump depend on the upstream Froude number and are classified as...

Unlike mitosis, meiosis aims for genetic diversity in its creation of haploid gametes. Dividing germ cells first begin this process in prophase I, where each chromosome—replicated in S phase—is now composed of two sister chromatids (identical copies) joined centrally.
The homologous pairs of sister chromosomes—one from the maternal and one from the paternal genome—then begin to align alongside each other lengthwise, matching corresponding DNA positions in a process...
