An insulated, cubical tank 1 meter on each edge is filled with water at 20oc. a cubical copper block 0.46 meters on each edge with an initial temperature of 1000c is quickly submerged in the water, causing an amount of water equal to the volume of the smaller cube to spill from the tank. an insulated cover is placed on the tank. the tank is adiabatic. estimate the equilibrium temperature of the system (

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

Athin walled concentric tube exchanger is used to cool engine oil from 160°c to 60°c with water that is available at 25°c acting as a coolant. the oil and water flow rates are each at 2 kg/s, and the diameter of the inner tube is 0.5 m and the corresponding value of the overall heat transfer coefficient is 250 w/m2. oc. how long must the heat exchanger be to accomplish the desired cooling? cpwater=4.187 kj/kg-candcpengine el=2.035 kj/kg·°c, oil . 120]
