1.)If dry hydrogen gas at atmospheric pressure is burnt completely in a furnace with 32 % excess air, calculate the Orsat analysis of the flue gas from this furnace
2.)A furnace uses a coal the ultimate analysis shows 57.22 % C, 5.64 % H, 1.41 % N, 5.06 % S, and 14.67 % ash. If the sulfur in the ash is negligible and the excess air is 80 %, compute the Orsat analysis of the combustion gases.
According to Jablonski diagram which transition is more favourable for carrying out a photochemical reaction?
(a)S₁→S₀
(b)S₂→S₀
(c)T₁→S₀
(d)S₁→T₁
In a photochemical reaction A→ B+C , the quantum efficiency with 500nm light is 1.2 x 10^2 mol.einstein^-1. After exposure of 200 millimoles of A to the light, 1.77 millimoles of B is formed.How many photons were absorbed by A?
What is the effect of varying the number of samples and the frequency as in the steps (7) and (8), respectively?
Why are the ripple absent in the synthesis of the periodic train of triangle pulse?

Why are the ripple absent in the synthesis of the periodic train of triangle pulse?
Calculate the volume percentage change as iron transform from FCC to BCC if the atomic radii are 1.270A and 1.241 A respectively
This section specially related to IoT application that you have asked to develop individually. This year we are dealing with Smart Agriculture/ farming or gardening applications and smart health home that are connected to many IoT sensor nodes to measure and deliver useful data. You are asked to prepare a complete designed report that describe,
· Sensors (2 or many)
· IoT processor/ controller
· Data transmission
· Data display for monitoring online
· Data storing and
· Complete software platform and other hardware related to interface to main processor.
· The design and development that you have produced will have far reaching applications in Domestic and commercial sectors.
Explain what uses an embedded system can have in current and emerging technology, critically evaluating such embedded applications, identifying trends and recognizing technical and economic factors.
