Ques:- WHY DO WE PROVIDE DEVELOPEMENT LENGTH AND EXTRA BARS AT TOP
Asked In :-
whirlpool corporation,
Right Answer:
Development length is provided to ensure that reinforcement bars bond properly with the concrete, preventing slippage and ensuring structural integrity. Extra bars at the top are added to accommodate tensile forces and enhance the strength of the structure, especially in areas where additional load or stress is expected.

Asked In :-
FIS Global Business Solutions India, Varite India, SWYM, Bobst India, STG Infotech INDIA LLP, Creditsafe Technology, Solugenix India, SRS Business Solutions (India), DhruvSoft, ANB Systems,
Right Answer:
SCADA (Supervisory Control and Data Acquisition) is a system for remote monitoring and control of industrial processes, often over large distances. DCS (Distributed Control System) is used for controlling production systems within a localized area, focusing on continuous processes. HMI (Human-Machine Interface) is the user interface that allows operators to interact with machines and systems, displaying data and enabling control.

Ques:- What is the Difference between E/P Positioner and I/P positioner in a control valve? In which applications the respective positioners are used in?
Asked In :-
Konkan Railway, Mumbai Metro One,
Right Answer:
E/P (Electro-Pneumatic) positioners convert an electrical signal (usually 4-20 mA) into a pneumatic signal to control a valve's position, while I/P (Current to Pressure) positioners convert an electrical signal directly into a pneumatic pressure signal. E/P positioners are typically used in applications requiring precise control of valve position, while I/P positioners are used in applications where a direct pressure output is needed for actuators.

Ques:- What is the dp across a orifice plate & how much ispermanent pressure across an orifice plate.
Asked In :-
Cenovus,
Right Answer:
The differential pressure (dp) across an orifice plate is the difference in pressure between the upstream and downstream sides of the plate, typically measured in psi or bar. The permanent pressure drop across an orifice plate is the pressure loss that occurs due to the flow restriction, which can be calculated using the orifice equation, but it generally results in a significant drop depending on the flow rate and the orifice size.

Ques:- What are the instrumental diagram of valve.
Asked In :-
Naval Group, columbia shipmanagement,
Right Answer:
The instrumental diagram of a valve typically includes symbols representing the valve type (e.g., globe, gate, ball), control mechanisms (e.g., actuator, positioner), and connections to the hydraulic or pneumatic system. It also shows the flow direction, pressure points, and any sensors or indicators associated with the valve operation.
