The choice of a dry screw compressor depends on several factors, including:nn1) Capacity: The required air flow rate and pressure determine the size and type of compressor needed. Larger capacities require larger units.nn2) Pressure Rating: The maximum pressure that the compressor can deliver is crucial for proper operation of downstream equipment.nn3) Material of Construction: The material selected should be compatible with the air quality requirements, such as resistance to corrosion and contamination from lubricants or seals.nn4) Duty Cycle: Continuous or intermittent operation dictates the choice between single-stage or two-stage compressors. Single-stage compressors are suitable for lower pressures and higher flow rates, while two-stage compressors deliver higher pressures at reduced flow rates.nn5) Efficiency: Energy efficiency is an important consideration to minimize operating costs. Modern dry screw compressors use energy-saving technologies such as variable speed drives and oil-free designs.nn6) Maintenance: The ease of maintenance, including accessibility for service, and the cost of spare parts should be taken into account when selecting a compressor.

Question 71 - (a) The byte is the basic building block of computer data used in chemical engineering process simulation where 16 bits make a word, 4 bits make a nibble, 32 bits make a quad word and 8 bits make a byte. Then how many nibbles are there in a megabytes? (b) In computer data items, let : 1 bit - counts from 0 to 1, 8 bits - counts from 0 to 255, 16 bits - counts from 0 to A. What is the value of A? (c) In a binary system of 4 bits, if 1100 = 12, 1101 = 13, 1110 = 14, 1111 = 15, B = 16, then guess the value of B. (d) By using any form of tools, find the exact value of 2 power 64 or 2^64.

ACCOUNTING AND FINANCIAL ENGINEERING - EXAMPLE 34.10 : Let D be the random outcome of rolling a dice once. A new dice has values of D* = D - 3.5. There is a total of n rolls of a dice. (a) Find the variance for D* by using the formula 6 V = [ D* (D = 1) ] [ D* (D = 1) ] + [ D* (D = 2) ] [ D* (D = 2) ] + [ D* (D = 3) ] [ D* (D = 3) ] + [ D* (D = 4) ] [ D* (D = 4) ] + [ D* (D = 5) ] [ D* (D = 5) ] + [ D* (D = 6) ] [ D* (D = 6) ]. (b) Calculate the standard deviation of D* as a square root of V. (c) Another new dice has values of D** = kD*. (i) Find the value of k so that D** has a standard deviation of 1. (ii) Find the values of D** for each outcome of D = 1, 2, 3, 4, 5 and 6, when the standard deviation is 1. (iii) Given that the average score of a dice is 3.5, find the equivalent, new and improved model of a dice, Sn in term of n and D**. (iv) Find the expected value of D** as the average of D**.
