I'm wondering with the circular fin, with uniform cross section area with given length and diameter. both ends are attached to surfaces. is there a general equation to find the heat rate by convection of the fin side surface. I tried to relate all the conditions and ended up with a equation that...

thank you very much !

the surface of the cyclinder is 4.89m^2 and the surface area for the ram is also 4.89m^2. and no i don't see any huge differences between those values. and when i tried to find the viscosity it give me the value of 1.4kg/ms or 14 P. I don't know if mine is correct or not :( could you check for...

Homework Statement An auto lift consists of a 55.56 cm diameter ram which slides concentrically in a 55.58 cm diameter cylinder (see Figure 1). The cylinder engages a 2.8 m length of the ram at all times. The annular region between the ram and cylinder is filled with viscous oil. The...

Omg thank you very much now I get it . but do you think I have to find H for the entering flow ?

It should be 1.3 x 34.387 = 44.7031 mol/min. I guess

It will be 34.487 mol/m^3

Homework Statement Prior to entering a combustion furnace, air is heated up from ambient temperature (25 °C) to 250 °C. This change in temperature causes the specific enthalpy to change to 3745 J/mol. Assume that the pressure of the air leaving the heater is 150 kPa and the flow rate is 1.3 m3...
