Apple juice at 20 C is siphoned from a large tank using a constant-diameter hose. The end of the siphon is 1 m below the bottom of the tank. Calculate the height of the hill over which the hose may be siphoned without cavitation. Assume properties of apple juice are same as water. The atmospheric pressure is 101.3 kPa. Height of the juice in the tank is 2 m.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

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?

Shafts are machine elements that are used to a) carry axial loads b) direct shear loads c) transmit power d) rotate at constant speed e) none of the above circular and square shafts subjected to the same torque under the same circum behave a) the same way b) almost the same way
