Hi, can you help me with the following problem? A thermally insulated tank of water 2 m x 2 m, depth 1 m is stirred with a paddle for threehours. If the paddle is driven by a motor whose shaft power is 8 kW determine the rate ofchange of temperature in degrees C per hr and the increase in temperature of the water.The specific heat of water is 4200 J/kgC. Identify a system and start your analysis from anappropriate form of the Fist Law of Thermodynamics
Using a 130 cm- long lead pipe with 2 cm inside diameter, a liquid water is transferred at 4 degrees Celsius. Its outside diameter measures 3 cm and the temperature of air outside is 20-deg C. The inside wall of the said pipe has a temperature of 8 degrees Celsius. Solve for: Outside area as basis, find (U) overall heat transfer coefficient
This question about heat transfer/liquid. A horizontal wire of circular cross section with a diameter of d=1 mm is heated with electric current, and 100W(q'=100W/m) heat energy is given to the wire from 1m length. The wire T∞ = temperature at 20 ° C, large, compared to that in a stagnant water body, locate the outer surface temperature of the wire.

36 -S 42 2. Metal castings can sometimes develop a gap between the casting and mold as the molten metal hardens. The result can be a substantially altered cooling process. Set up a simple heat-transfer model that would let you look at the effect of the gap on the cooling process. Assume the casting and mold are square in shape, with an air gap of thickness das shown in the figure. The mold sits in some ambient room temperature. State clearly all assumptions and develop a corresponding model of the heat transfer problem. Assuming that the casting is aluminum, the mold is diatomaceous earth and the gap is filled with air, see if you can arrive at and summarize some insight into the effect of the gap and its size on the heat transfer process.

A conditioned space has a calculated heat loss at the design maximum heating day of 10,000 BTUs / Hr to maintain an interior temperature of 70 F. We will use a hydronic baseboard style convector to heat the space. The style we have chosen comes in standard lengths. At rated temperature and flow of hydronic heating fluid for each 1 foot of length the heater will add 750 BTUs /Hr to the room. What length of heater can just maintain the temperature on the worst day? For this example we are ignoring other sources of heat loss such as ventilation or drafts.
