31. A pressure difference of 500 Pa is available to force 20oC air through a circular sheet-metal duct 450 mm in diameter and 30 m long. At 20oC, p = 1.204 kg/m3 and take friction factor, f = 0.016. Determine the velocity.
30. Compute the pressure drop of 35oC air flowing with a mean velocity of 7 m/s in a circular sheet-metal duct 450 mm in diameter and 25 m long. Use a friction factor, f = 0.04, and Pair = 1.3799 kg/m3.
Describe the metal-chelating antioxidant activity of quercetin.
29. A coil has an inlet temperature of 70oF and outlet of 80oF. If the mean temperature of the coil is 120oF, find the bypass factor of the coil.
28. Compute the specific volume of an air-vapor mixture in cubic meters pre kilogram of dry air when the following conditions prevail : t = 45oC, w = 0.015 kg/kg, and Pt = 100 kPa.
27. A classroom that normally contains 40 people is to be air-conditioned with window air-conditioning units of 5 KW cooling capacity. A person at rest may be assumed to dissipate heat at a rate of about 360 KJ/hr. There are 10 light bulbs in the room, each with a rating of 100 watts. The rate of heat transfer to the classroom through the walls and the windows is estimated to be 15,000 KJ/hr. If the room air is to be maintained at a constant temperature of 21oC, determine the number of window air-conditioning units required.
26. An auditorium seating 1600 people is to be maintained at 80oF dry bulb and 65oF wet bulb temperature
when outdoor air is at 91oF dry bulb and 75oF wet bulb. Solar heat load is 120,000 Btu/hr and supply air is
at 60oF, determine the amount of supply air. (Use sensible heat load of 225 Btu/hr per person).
In the examination, Rajiv is asked to write a python function to demonstrate the use of the "+" operator. During the examination, Rajiv got confused that either he needs to add two numbers using "+" or concatenate two strings. So, Rajiv decided to implement both cases in his python code. Your task is to help Rajiv by writing a python function Add_Values(a,b)
