PLEASE ANSWER PART B (part a is there for reference)
For each of the conditions given below find the outdoor
temperature that gives you condensation on the
inside
window surface. Part (a) is the reference case by which all of the
other cases can be compared. In each case, the
indoor temperature and humidity is fixed at 70°F and 50%
respectively, which as you know from a chart gives you a
dew point temperature of about 51°F. .
a. Inside and outside convective heat transfer is 1.46 and 6
Btu/hr.ft 2 °F respectively, while the thermal
resistance for single pane 1/8 inch thick glass is 1.0 hr.ft 2 °
F/Btu,. ( use thermal resistance networks )
b.Same as Part (a) except the outside wind velocity increases so that h=12 Btu/ hr.ft 2 .

Heat Transfer
Problems 1. A window pane (1/8 inch thick) in an old house owned by a professor is 3 ft. by 4 ft. He likes to be warm in the winter so the inside temperature is kept at 70 °F even when the outside temperature is 10 •F. For this problem assume the inside and outside temperatures are for the window surface. How much heat is transferred through the window (k=.54 BTU/hr ft ° F)? 2. A small heated...

1. A ¾ inch (nominal), Schedule 40, mild steel pipe carries 40 psia steam through a room having an air temperature of 80°F. The pipe is covered with a 0.125 ft thick layer of fiberglass insulation having a thermal conductivity of 0.037 Btu/(h ft ‘F). The hi value on the steam side of the pipe is 1000 Btu/h ft2 °F. The ho value on the outside of the insulation is 2.0 Btu/(h ft2 ’F). For the mild steel, k=26Btu/(ft H...

Assume the above air enters an evaporator coil at 90°F where it is cooled in a constant humidity ratio process until reaching the 100 % RH curve ( the temperature at that point is the dew point. The air then keeps dropping in temperature, following...
