Using the Lumen Method to find out how many fittings are required for a square conference room which requires 500 lux from CIBSE Guide, of area 200 m2, using the T5 fluorescent fittings at 1.2 meter long each and at 2 m high measured from the light source to the working surface.
The 1.2m T5 luminaire has 2700 lumens each.
Your answer should mention about all the light losses, say, due to surface reflectance at ceiling, wall and floor, light loss factor, maintenance factor, etc,.

Please refer to the article titled as “Sustainable Construction Excellence for a Better Future in Malaysia, published in The Ingenieur, Vol. 69 January – March 2017 by the Board of Engineers Malaysia. Identify the key challenges in sustainable construction and what should be undertaken to achieve sustainable cities?

A manufacturing process produces piston rings, with ID (inner diameter) dimension as shown above. Process variation causes the ID to be normally distributed, with a mean of 10.021 cm and a standard deviation of 0.040 cm. a. What percentage of piston rings will have ID exceeding 10.075 cm? What percentage of piston rings will have ID exceeding 10.080 cm? (4) b. What is the probability that a piston ring will have ID between 9.970 cm and 10.030 cm? (This is the customer’s specification that the supplier tries to provide .) (ie.) If the specification is “9.970cm < ID < 10.030cm”, what %’age of piston rings are “out of spec”? c. Half (50%) of all piston rings have ID below 10.021 cm. What is the dimension corresponding to the smallest 10%, and what is the dimension corresponding to the largest 10%? What is the dimension corresponding to the smallest 20%, and what is the dimension corresponding to the largest 20%

2. (10 pts) Air (R = 0.287 kJ/kg.K) enters the compressor of a simple Brayton cycle at 94 kPa and 7^oC. The pressure ratio is 19.2, the compressor efficiency is 81%, the turbine inlet temperature is 1600 K and the turbine isentropic efficiency is 85%. The mass flow rate is 21 kg/s. Using variable specific heat analysis, determine:
   1. (2 pts) The power input to the compressor, in kW.
   2. (2 pts) The rate of heat input in the combustion chamber, in kW.
   3. (3 pts) The net power produced by the engine, in kW.
   4. (1 pt) The overall efficiency
   5. (2 pts) The density of the air exiting the compressor, in kg/m³.

            What do we mean when we say “a preferred size”? Explain and give an example.

A cylindrical storage tank contains liquefied propane under a pressure of 1.5 MPa (gage pressure P=1.5 MPa) and is subjected to a torque T=5 kN-m. Knowing that the tank has an inner diameter of 320 mm and a wall thickness of 3 mm, find the principal stresses and determine the maximum shear stress.

4. A device used to expose fighter pilots to high g’s that they might experience in action incorporates a small cockpit on the end of a 50 ft. long radial shaft that is attached to the cg. of the cockpit. The cockpit and pilot weigh 600 lb total. If there is a motor that provides a torque of 1000*sqrt(t) ft-lb to the system, calculate the following:
   1. How fast does the cockpit have to travel to produce 6 g’s?
   2. How long does the system take to get to that speed?

Assume you have a metal alloy - an aluminum alloy for example - that has been welded and then heat treated in a way that leaves you uncertain as to the microstructure. Since the component is to be used for a critical application, you want to be sure of both the structure and mechanical properties. You want to create a single phase structure so that you can "start over" with a new heat treat cycle to more exactly and carefully create the desired properties. What type of heat treatment would you use to create the single phase structure?

1. Write a report on advancement in wheel and tyre technology.Also the report should be consest of 10-12 Page,Advantage disadvantage,Future scope.Plagarsim level should be Zero.

Please don't answer if you don't know and write the report on 10-12 page minimum.
For small answer or for plagrism I will downrate your answer.So if you know than only answer it

8. Figure 1 shows an artificial neuron. If the node has three inputs and could receive only binary signals (either 0 or 1), what are the input pattern it can receive?

Fluid (air) enters a nozzle at 150 m/s, 26.85 oC, and at a pressure of 200 kPa. Assuming isentropic flow, evaluate the temperature and pressure of the fluid at a location where the speed of fluid equals the speed of sound. What is the ratio of the area at this location to the entrance area?

The spray characteristics of a highly toxic liquid fuel, especially particle their diameter is required. In the examination, the particle diameter dp, spray outlet rate U, liquid viscosity µ, surface tension Y, density ρ and spray it is suggested that the spray injector is connected to the outlet diameter D and is safe it is suggested that an experiment can be carried out with water, design and state the requirements for the creation of this experiment and obtain how to use your data for prototype fuel in mathematical terms If necessary, write with dimensionless numbers.
