Air is contained in a piston cylinder device, it expands first isothermally (1=>2) then isobaric expansion takes place (2=>3). The processes on the T-v diagram will be: Select one: A. (1-2) Horizontal line, (2- 3) Inclined line with Positive slope. B. (1-2) Horizontal line, (2- 3) Inclined line with Negative slope. c. (1-2) Inclined line with Positive slope, (2-3)

Heat transfer by conductivity: One side of a 3 cm thick copper plate is held at 400°C and the other at 100°C. How much head transferred through the plate?

Q2: For the pipeline system shown in Figure, determine the value of (Pg-PA). Glyceria SG =126 Water SG = 1.0 Oil SG=0.88 55 cm 10 em 12 cm 20 cm Mercury SG = 13.5 (30 Degree)

(answer number 4-8 & main question) Two vessels of different shape and sizes are connected by means of a pipe with a valve. Vessel A has a diameter of 4 ft and the length is 1.8 m at the given pressure gauge of 1476.4 in Hg and temperature of 82°F. Another vessel spherical in shape contains the same gas at 15,000 torr gauge and 18°C. The valve is opened and when the properties have been determined, it is found out that the gauge pressure is 35.7 kgf/cm2 and the temperature is 21°C. If the barometric pressure is 755 mm Hg, find the following: Volume of Vessel A in in3 - done  Pressure at Vessel A in psia - done Temperature at Vessel A in °R - done Pressure at Vessel B in psia Temperature at Vessel B in °R Pressure of the gas when mixed in psia Temperature of the gas when mixed in °R Atmospheric pressure in psi Main Question: What is the diameter of the spherical tank in inches if the gas is carbon dioxide?

W m-°C. 1.)A 2mx2m aluminum sheet (240 is 5mm thick and used to separate two types of gas (1.1) and (55) in an experimental chamber. The 1st type of gas is maintained at 20℃ while the 2nd gas is at -20C. Solve for the rate of heat transfer in kW.
