A 15 cm x 20 cm hot surface at 85 degrees is to be cooled by attaching 4 cm long aluminum (k= 237 w/m degrees C) fins of 2 mm x 2 mm square cross section. The tempurature of surrounding medium is 25 degrees C and the heat transfer coefficent of the surfaces can be taken to be 20 W/m^2 degrees C. If it is desired to triple the rate of heat transfer from the bare hot surface, determine the number of fins that needs to be attached.
a 0.075 kg ice cube at 0 degree c is dropped into an insulated styrofoam cup holding 0.33 kg of water at 25.0 degree c.
A 1 m steel rod (circular cross-section) has a diameter of 2 cm and is pulled in tension with a load of 50 kN. The steel rod experiences an entirely elastic elongation of 1 mm. a) Calculate the elastic modulus of the steel. b) Calculate the diameter ..
Air is compressed adiabatically from p1 = 100 kPa, T1 = 300 K to p2 = 1500 kPa, v2 = 0.1227 m3 /kg. The air is then cooled at constant volume to T3 = 300 K. Assuming ideal gas behavior and neglecting kinetic and potential energies, calculate the work..
Draw a force diagram and obtain a differential equation for ω. This equation is quite simple and can be solved either by inspection or by formal integration.
