- Water in a tank is to be boiled at 143.27 Pa absolute pressure by a 1.5-cm-diameter brass heating element equipped with electrical resistance wires inside, as shown in the figure. Determine the maximum heat flux that can be attained in the nucleate boiling regime and the surface temperature of the heater in that case. (3.23x105 W/m2, 118.6°C)arrow_forwardIn boiling water at 1 atm pressure outside a stainless-steel tube with a surface temperature of 410F, the heat-transfer coefficient h in the absence of radiation is 32 Btu/h*ft^2*F. If the emissivity of the stainless steel is 0.8, will radiation significantly augment the rate of boiling (e.g., by more than 5 percent)? Assume that the vapor film is transparent to radiation and the boiling liquid is opaque.arrow_forwardWhat is boiling and when does occurs? Explain pool boiling. How does it differ from forced convection boiling?arrow_forward
- In what kind of pot will a given volume of water boil at a higher temperature: a tall and narrow one or a short and wide one? Explain.arrow_forwardWhat is condensation and when does occurs? How does filmwise condensation differs from drop-wise condensation? Which type has a higher heat transfer film coefficient and point out the reason thereof?arrow_forward(About measuring specific heat capacity) Since metal sample can be heated to any desired temperature value, say, 65°C or 156°C. Why is it practical to set the initial temperature of the metal sample near the boiling point of water? In connection to this, why should the dipper be partly submerged in the water while heating the metal sample?arrow_forward
- What are the surface condensing systems? Explain their working.arrow_forwardConsider a pan of water being heated by placing a heating element in the water. Which method is a more efficient way of heating water? Explain.arrow_forwardWhich boiling mechanism is characterized by a drop in heat transfer with respect to the increase in temperature difference between the heated surface and the fluid? A.
