What do you need to find the operating point of the system?
- The characteristics of the pump
- The pump characteristic curve
- The characteristic curve of the system
- The characteristic curve of the pump and system
What part of the pilot plant measure the pressure difference?
- The differential pressure sensor
- The diaphragm and manometers
- The diaphragm and the pressure sensor
- The diaphragm
How is calculate the volumetric flow meter with the flow?
- Dividing the flow for 60 seconds
- By dividing the flow time measurement
- Multiplying the flow for 65 seconds
- Gives the volumetric flow directly
Mark the correct answer:
- The mass flow are different between points 1 and 2.
- Call characteristic curve of the pump when the height increases as the volumetric flow is greater.
- In an ideal fluid, the viscosity is different from 0.
- NPSH parameter helps us not cavitation occurs.
What is the parameter that defines the cavitation?
- Volumetric flow
- The power
- The characteristics of the pump that gives the manufacturer
- NPSH
Mark the correct answer:
- The velocity at points 1 and 2 are identical.
- Volumetric flow at points 1 and 2 are different.
- The energy and mass flow are different in points 1 and 2.
- The section at points 1 and 2 are identical.
What is the cavitation occurs?
- A very high frequency, causing the fluid passing through the pump at high speed.
- The phase change of the fluid inside the pump.
- A sudden increase in pressure.
- It provides a higher flow rate.
Why is purged from the tubes of the diaphragm?
- Not to deteriorate the pressure sensor.
- That air bubbles can damage the device.
- Bubbles may give an erroneous measurement.
- It's not necessary.
Why the height decreases with increasing flow?
- The pressure difference created between P1 and P2.
- By increasing the volumetric flow that circulates through the pump.
- Unlike the mechanical and hydraulic power.
- By the increased force that is created.
How to establish the characteristic curve of the installation?
- From the different frequencies.
- From the different velocities in the pipes.
- From the decrease in height over time.
- Since the loss of pressure in the pipes.
