Hetero QC Interview Questions and Answers

Qualitative research is subjective and exploratory while quantitative research is objective and numerical.

• Qualitative research is used to gain an understanding of underlying reasons, opinions, and motivations while quantitative research is used to quantify data and generalize results from a sample to the population.

• Qualitative research uses non-numerical data such as words, images, and observations while quantitative r...read more

A PID temperature indicator controls temperature by adjusting heating/cooling based on feedback from sensors.

• PID stands for Proportional-Integral-Derivative, which are the three control modes used to adjust temperature.

• The indicator receives input from temperature sensors and compares it to the desired temperature setpoint.

• Based on the difference between the two, the PID controller adjusts the heating/cooling output to...read more

Utility distribution systems ensure efficient delivery of essential services like water, electricity, and gas to designated areas.

• Design involves assessing the demand for utilities in the block based on population and usage patterns.

• Incorporate sustainable practices, such as using renewable energy sources for electricity distribution.

• Example: For a residential block, design a grid layout for electricity that minimizes ...read more

MTSR, DSC, and TSC are metrics used in call centers to measure performance and efficiency.

• MTSR stands for Mean Time to Service Request and measures the average time it takes for a customer's service request to be resolved.

• DSC stands for Delayed Service Calls and measures the number of service calls that were not resolved within a certain timeframe.

• TSC stands for Total Service Calls and measures the total number of serv...read more

The degree of freedom of water at triple point is 0.

• Triple point is the temperature and pressure at which solid, liquid, and gas phases of a substance coexist in thermodynamic equilibrium.

• At triple point, the degree of freedom of a substance is zero because all three phases coexist in equilibrium.

• Water has a triple point at 273.16 K (0.01 °C) and a pressure of 611.73 Pa.

• At triple point, water can exist as ice, liquid w...read more

The power required for a pump can be calculated using the formula: Power = (Flow rate x Head) / Efficiency

• Calculate the flow rate of the pump

• Determine the head or pressure required

• Consider the efficiency of the pump

• Use the formula: Power = (Flow rate x Head) / Efficiency

• Example: If the flow rate is 1000 liters per minute, the head is 50 meters, and the efficiency is 80%, the power required would be (1000 x 50) / 0.8 = ...read more
