Nektar Therapeutics Interview Questions and Answers

Q1. Why humidity is require?
Ans. 
Humidity is required to maintain a comfortable and healthy environment, prevent static electricity, preserve certain materials, and support plant growth.
• Maintains a comfortable environment by preventing dryness in the air

• Helps prevent static electricity buildup, which can damage electronics

• Preserves certain materials like wood, leather, and musical instruments

• Supports plant growth by providing necessary moisture for ph

Q2. At what time humidity will increase?
Ans. 
Humidity typically increases during the night and early morning hours due to cooler temperatures and higher relative humidity.
• Humidity tends to increase during the night when temperatures drop and air can hold less moisture.

• Early morning hours also see an increase in humidity as temperatures start to rise and dew forms.

• Factors such as proximity to bodies of water, vegetation, and weather patterns can also influence hum...read more

Q3. Why HEPA filter is 0.3 micron?
Ans. 
HEPA filters are designed to capture particles as small as 0.3 microns due to their ability to efficiently trap particles of that size.
• HEPA filters are designed to capture particles of various sizes, including very small particles like viruses and bacteria.

• 0.3 microns is considered the most penetrating particle size, meaning particles of this size are the most difficult to capture.

• HEPA filters are able to efficiently t...read more

Q4. How to calculate blower CFM?
Ans. 
Blower CFM can be calculated by multiplying the air velocity by the cross-sectional area of the duct.
• Calculate the cross-sectional area of the duct (in square feet or square meters)

• Measure the air velocity (in feet per minute or meters per second)

• Multiply the air velocity by the cross-sectional area to get the CFM

• Example: Cross-sectional area = 5 sq ft, Air velocity = 100 ft/min, CFM = 5 sq ft * 100 ft/min = 500 CFM

Q1. If you dont have technical description of BLower.and you have to order. Which type of measurement you will take?
Ans. 
I would take measurements such as airflow rate, pressure, power consumption, and noise level to determine the appropriate blower for ordering.
• Airflow rate: measure the volume of air moved per unit of time

• Pressure: measure the force exerted by the blower to push air

• Power consumption: measure the amount of electrical power needed to operate the blower

• Noise level: measure the sound produced by the blower during operation

Q2. How to calculate friction loss?
Ans. 
Friction loss can be calculated using the Darcy-Weisbach equation, which takes into account the pipe material, diameter, length, flow rate, and roughness factor.
• Use the Darcy-Weisbach equation: f = (4 * f * L * V^2) / (2 * g * D)

• Where f is the friction factor, L is the length of the pipe, V is the flow velocity, g is the acceleration due to gravity, and D is the diameter of the pipe.

• Friction factor can be determined ba...read more

Q3. Why we mainten water velocity of RO water and how much?
Ans. 
Maintaining water velocity of RO water is crucial for efficient filtration and production of high-quality water.
• Maintaining water velocity ensures proper pressure and flow rate for effective filtration process

• Optimal water velocity prevents fouling and scaling of RO membranes

• Recommended water velocity for RO systems is typically between 0.5 to 2 meters per second
