A Zener diode is used for
- voltage stabilisation.
- rectification.
- voltage regulation.
Isn't regulation the same as stabilization?
Capped nuts are used so
- to prevent leaks from pipe ends.
- the part is not over torqued as the bolt touches the captive part first.
- to ensure that it is dry bolted.
for this question the answer is part not over torqued as bolt touches the captive part first..
meanwhile for this question, the answer is to stop leak:
Capped nuts are used
• prevent overtightening due to the threaded portion being restricted by the cap.
• to provide a dry torque joint.
• to stop leaks.
care to explain anyone?
Which of the following influences the operation of an automatic fuel control unit on a turbojet engine?
- Exhaust gas temperature.
- Mixture control position.
- Burner pressure.
If combustion occurs at CONSTANT pressure, does anyone know how the FCU can be "influenced" by burner pressure??
In a gas turbine engine, turbine section
- temperature decreases along with pressure and velocity.
- velocity decreases and pressure increases.
- velocity increases and pressure decreases.
Debate: Does velocity (dynamic pressure) drop across the whole turbine section? Obviously V increases as it passes through the nozzle guide vanes (convergent) but after passing through each turbine stage the velocity overall will decrease.?
Which will weigh the least?
- 98 parts of dry air and 2 parts of water vapour.
- 50 parts of dry air and 50 parts of water vapour.
- 35 parts of dry air and 65 parts of water vapour.
