MJA PharmaTech Junior Process Engineer Interview Questions, Process, and Tips

The main criteria for line sizing is to ensure proper flow rate and pressure drop within the system.

• Consider the required flow rate of the process fluid

• Calculate the pressure drop allowed in the system

• Select a line size that can accommodate the flow rate and pressure drop requirements

• Take into account factors such as fluid properties, pipe material, and system layout

• Use engineering standards and guidelines for sizing p

Pump characteristics curve shows the relationship between flow rate, head, efficiency, and power consumption.

• The curve typically consists of a series of lines or curves representing different pump speeds or impeller diameters.

• It helps engineers select the right pump for a specific application by analyzing the performance at different operating points.

• The curve shows how the pump's performance changes with variations in...read more

The API code for breather valves is API 2000.

• API 2000 is the standard code for breather valves in the industry.

• Breather valves are also known as pressure/vacuum relief valves.

• API 2000 provides guidelines for the design, installation, and maintenance of breather valves.

The energy required to heat water using steam can be calculated using the formula: Energy = mass of water x specific heat capacity of water x temperature change + mass of water x latent heat of vaporization of steam

• Calculate the energy required to raise the temperature of water from initial temperature to desired temperature using the formula: Q = mcΔT

• Calculate the energy required to convert water to steam at the boili...read more
