A six cylinder 3.2-liter engine operates on a four-stroke cycle at 2400 RPM. The compression ratio is 10.2:1. The bore and stroke are related as S=1.12*B. Calculate: 1. Clearance volume of one cylinder in cm3, L and in in3. 2. Bore and stroke in cm and in 3. Average piston speed in m/sec and ft/sec 4. Piston speed when the crank angle is θ=90° aTDC in m/sec

Apipe with an outside diameter of 15 cm is exposed to an ambient air and surrounding temperature of -20°c. the pipe has an outer surface temperature of 65°c and an emissivity of 0.85. if the rate of heat loss from the pipe surface is 0.95 kw per meter of length, the external convective heat transfer coefficient (h) is: (a) 12.5 w/m"k (b) 18.6 w/mk (c) 23.7 w/mk (d) 27.9 w/mk (e) 33.5 w/mk

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
