A remote control valve functions as a _______________ valve.
Show answer Hide answer
Answer: B. Butterfly
Explanation
Butterfly valves feature a rotating disc that provides rapid quarter turn flow control operation. Their design enables easy automated actuation, making them ideal for remote control applications. Actuators can be attached to butterfly valves to regulate industrial pipeline flow remotely. Butterfly valves consist of a flat circular disc positioned in the center of the pipe conduit. Quarter turn rotation moves the disc from fully closed to fully open positions rapidly. They offer compact installation dimensions and lower pressure drops compared to globe valves.
Water treatment plants use automated butterfly valves for remote flow regulation in large headers. HVAC systems employ pneumatic butterfly valves to control conditioned airflows through large ducts. Industrial chemical facilities utilize remote actuated valves for emergency process isolation. Option a lists gate valves, which require multi turn handwheels unsuited for quick remote actuation. Option c mentions needle valves, which are used for fine manual throttling rather than automated control. Option d describes globe valves, which are bulky and generally operated manually with multi turn stems.

Answer: C. Are not subject to air binding
Reciprocating pumps are positive displacement machines that physically push trapped fluid volumes. Because they displace fixed volumes per stroke, they easily force out gas pockets and avoid air binding. This mechanical...
Q2. What is the primary function of an air lift pump____________________?
Show answer Hide answer
Answer: C. Lift water from a well by using compressed air
Air lift pumps use compressed air injected into a submerged vertical pipe to lift water from wells. Injected air mixes with the water, reducing the effective fluid column density inside the pipe. The higher hydrostatic p...
Q3. Water flows through a 5 cm ID tube with a Reynolds number of 1500. If a liquid with 5 cP viscosity and 0.8 specific gravity flows through the same pipe at identical velocity, how will the pressure drop compare______________________?
Show answer Hide answer
Answer: A. Increase
Higher fluid viscosity increases internal shear stresses and frictional resistance within pipe networks. Increased friction factor values directly elevate the total pressure drop for identical flow velocities. Therefore,...
Q4. Rubber latex is classified as a ______________ fluid.
Show answer Hide answer
Answer: A. Pseudo plastic
Rubber latex exhibits non Newtonian flow behavior where apparent viscosity decreases under shear stress. Fluids that thin out under applied shear without requiring a yield stress are termed pseudo plastic. Polymer soluti...
Q5. Which scenario illustrates steady non-uniform flow accurately?
