It contents all type of Flow Measuring devices like Orificemeter, Venturimeter, Rotameter Etc. There are several types of flowmeter that rely on Bernoulli's principle. The pressure is measured either by using laminar plates, an orifice, a nozzle, or a Venturi tube to create an artificial constriction and then measure the pressure loss of fluids as they pass that constriction or by measuring static and stagnation pressures to derive the dynamic pressure.

Classification of Pneumatic Elements Included Valves, CompressorMohammad Azam Khan
Pneumatic systems range from simple air-driven pistons to multiple-actuator mining operations. All pneumatic systems use a source of compressed air to power moving parts, or actuators. Pneumatic systems commonly use compressed atmospheric air, as it is abundant and inexpensive. Atomized oil is added to the air in some blends to ease its passage through mechanical systems. Pneumatic systems are generally preferred over similar, liquid-using hydraulic systems, due to their quietness, ease of use and cost efficiency.
In this day and age of automated computer control valve sizing, the logic and theories behind it are invisible. In his presentation, Al Holton of Allagash Valve & Controls will look at the basic principles that apply and how they affect the application and installation of a wide range of control valve types. He will also review the reasoning behind valve type selection.
This was one of the very first CBT modules I developed. This presentation was imported into Captivate, where additional features such as mouse-over definitions were added.

100++-interview questions and answers on steam turbine
Is it possible to have a negative absolute pressure?
No, absolute pressure is measured with reference to a perfect vacuum so it is impossible for it to go negative. You can only measure negative pressure between two different pressures. For example if you allow atmospheric air to gradually flow into a vacuum vessel and measure pressure inside relative to outside it will show a negative pressure reading.
What type of problems do you face in steam turbines related to vacuum?
Problems such as:
· Low vacuum
· High exhaust pressure
· High exhaust temperature
· Higher specific steam consumption
· More cooling water circulation
· Hot well level variation
How do you create vacuum in steam condensers?
Vacuum is created in condenser by steam jet ejectors, where high pressure 8–12 kg/cm2 steam is passed through nozzle which is connected to air line from condenser. This creates high negative pressure there by evacuating air from condenser.
Generally there are Two Types of Ejectors:
Hogger Ejector: Initially this ejector is used for pulling vacuum. It has steam and air lines connections, steam is vented directly into atmosphere. It consumes more steam than main ejectors. It requires 20–30 minutes to create 85% of operating vacuum.
Main Ejector: It comes with first stage and second stage. Air line from surface condenser is given to 1st stage then again air from 1st stage is collected and discharged into 2nd stage. 2nd stage ejector has air vent line.
It consumes less steam than hogger ejector. Generally an ejector come with 1W + 1S i.e. one working and one stand by.
Also vacuum pumps called liquid ring vacuum pumps are used to create vacuum in condensers. Which consume less energy than steam jet air ejector
How does low vacuum affect on turbine speed?
Lower vacuum creates back pressure on turbine blades and rotors. So in emergency, vacuum breaker valve is opened to bring down the turbine speed to zero in minimum time to avoid any further damages.
What is the effect of low vacuum & high exhaust pressure on steam turbine performance?
Low vacuum or high exhaust pressure & high exhaust temperatures lead to more steam consumption to generate unit power.
What are the potential reasons for lower vacuum in steam condenser?
· More condenser load than design
· Lesser amount of cooling water circulation in condenser
· Higher atmosphere temperature
· Location of the steam condenser at higher elevations.
· More exhaust temperature
· Air leakages in the system
· Lesser efficiency of steam ejector or vacuum pump
· Ejector inter condense (1st stage) condensate seal break
· Lesser pressure & temperature of motive steam at ejector inlet
· Worn out ejector nozzles
· Improper quality of motive steam
· Variation in condenser inlet & outlet cooling water temperatures
· Operation of Turbine at lower load
· Lower gland seal steam pressure

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
