Idyllic Services Interview Questions and Answers
Q1. Any cost reduction experience related to process plants?
Yes, I have experience in implementing cost reduction strategies in process plants.
Implemented lean manufacturing principles to reduce waste and improve efficiency
Optimized equipment maintenance schedules to minimize downtime and reduce costs
Negotiated better pricing with suppliers to lower material costs
Introduced automation technologies to streamline processes and reduce labor costs
Q2. What is Coefficient of Control valve?
The coefficient of a control valve is a measure of the valve's flow capacity relative to the pressure drop across it.
The coefficient of a control valve, also known as the flow coefficient (Cv), is a dimensionless number that represents the flow capacity of the valve for a given pressure drop.
It is used to compare the performance of different valves and is typically determined experimentally.
A higher coefficient indicates a greater flow capacity for a given pressure drop.

Q3. What is pump hydraulic calculation?
Hydraulic calculation for pumps involves determining the flow rate, pressure, power, and efficiency of a pump system.
Calculate flow rate using the formula Q = VA, where Q is flow rate, V is velocity, and A is cross-sectional area.
Determine pressure using the formula P = F/A, where P is pressure, F is force, and A is area.
Calculate power using the formula P = Q*H*rho*g, where P is power, Q is flow rate, H is head, rho is fluid density, and g is acceleration due to gravity.

Q4. Describe Detailed Pump hydraulic calculation?
Pump hydraulic calculation involves determining the pump head, flow rate, and power requirements for a specific system.
Calculate total dynamic head (TDH) by adding the static head, friction head, and velocity head
Determine the required flow rate based on system requirements
Calculate the pump power requirements using the formula: Power (kW) = (Q x TDH) / (3.6 x efficiency)
Consider factors such as pump efficiency, pipe size, and fluid properties in the calculations
Q5. Troubleshooting experience in process plants?
I have extensive troubleshooting experience in process plants, identifying and resolving issues to ensure smooth operations.
Identifying root causes of process issues
Developing and implementing solutions to improve efficiency
Collaborating with cross-functional teams to troubleshoot complex problems
Utilizing data analysis and problem-solving skills
Adapting quickly to changing situations and priorities
Q6. What are types of pumps?
Types of pumps include centrifugal pumps, positive displacement pumps, and axial flow pumps.
Centrifugal pumps: use a rotating impeller to increase the pressure of a fluid.
Positive displacement pumps: trap a fixed amount of fluid and then force it into a discharge pipe.
Axial flow pumps: move fluid parallel to the pump shaft.
Examples: Centrifugal pump - water pump, Positive displacement pump - diaphragm pump, Axial flow pump - propeller pump
