The heat transfer rate from internal water flow which enters at 25°c and exits 15ºc is 5768 w. the pipe diameter is 0.15m and outside temperature kept at 0 c. the fluid property at the average temperature of 20°c as follows: •v==1.006x10-6 m/s2 • k=0.597w/m. k pr=7.02 u=0.16m/s estimate the required length for this heat transfer?

Which type of reaction always has an element and a compound as reactants

Listen base your answer to the question on the information below. propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below. c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol. what is the correct structural formula for a molecule of methanethiol

Ab c or d ? i’m not sure what the answer is
