(a) Explain various process of Carnot cycle with the help of P-V and T-S diagrams and mention various assumptions made in the analysis of Carnot cycle.
(b) The following details refers to a four stroke engine:
Cylinder diameter = 220 mm
Length of stroke = 330 mm
Speed = 5 rev/second
Effective brake load = 500 N
Mean circumstances of the brake drum = 4·5 m
IMEP = 5·6 bar
Calculate
(a) Indicated power, (b) Brake power and (c) Mechanical efficiency.
What are different methods adopted in cooling of an I.C engine. Explain in details.
(a) A Diesel engine has a bore of 200 mm and stroke of 320 mm. Cut – off takes place at 9% of stroke. Find the air – standard efficiency if clearance volume is 0.000593 m3.
(b) An engine working on Otto cycle has a compression ratio of 6. Find the air – standard efficiency of the cycle.
A water manometer shows a pressure, in a vessel of 400mm below atmospheric pressure. If the atmospheric pressure is measured as 763 mm Hg. Determine absolute pressure in the vessel in kN/m2
Draw a paging hardware for a 64-byte memory with 4-byte pages.
Discuss the effective measures of urban noise control from the perspective of urban functional area division
Explain the Secondary Memory and its signification in computer system in detail with help of well
labeled diagrams?
computer employs RAM chips of 512 x 8 and ROM chips of 256 x 8. The computer system needs
1K bytes of RAM, 2K bytes of ROM, and eight interface units, each with 2 registers. A memory-mapped
1/0 configuration is used. The two highest-order bits of the 16 bit address bus are assigned 10 for RAM,
11 for ROM, and 00 for interface registers.
a. How many RAM and ROM chips are needed?
b. Draw a memory-address map for the system.
c. Give the address range in hexadecimal for RAM, ROM, and interface.
Explain the Advantages and disadvantages of 3 mapping techniques between main memory to cache
memory in the tabular form. show how and from where CPU will access the word from the cache
memory in each mapping technique with the help of diagram. Take the word number as per your roll no.
for example if your roll no is 35 than you have to show how and from where CPU will access W35 from
the cache memory with the help of diagram. Assume the main memory size as 8 KB, line size 128 bytes,
cache size 2 K bytes and k value is 2 .
Identify and explain the mode of data transfer in which CPU continuously monitor the status register for transferring the data. Support your answer with a neat and clean diagram.
