A0.468 g sample of pentane, c 5h 12, was burned in a bomb calorimeter. the temperature of the calorimeter and 1.00 kg of water in it rose from 20.45 °c to 23.65 °c. the heat capacity of the calorimeter by itself is 2.21 kj/°c and the specific heat capacity of water is 4.184 j/g.°c what is the heat of combustion per mole of pentane?

This is how zirconium appears in the periodic table. rounded to the nearest whole number, how many electrons are in an atom of zirconium?

Asteel tube (k=50 w/mk) of inner and outer diameter di = 20mm and do=26mm, respectively, is used to transfer heat from hot gases flowing over the tube (h-hot = 200w/m2k) to cold water flowing through the tube (h-cold = 8000 w/m2k). what is the cold-side overall heat transfer coefficient uc? to enhance heat transfer 16 straight fins of rectangular profile are installed longitudinally along the outer surface of the tube. the fins are equally spaced around the circumference of the tube, each having a thickness of 2mm and a length of 15mm. what is the corresponding overall heat transfer coefficient uc? *solve for uc in both cases*
