Arigid, insulated tank that is initially evacuated is connected through a valve to a supply line that carries steam at 4 mpa. now the valve is opened, and steam is allowed to flow into the tank until the pressure reaches 4 mpa, at which point the valve is closed. if the final temperature of the steam in the tank is 600°c, determine the temperature of the steam in the supply line and the flow work per unit mass of the steam.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

The filament of an incandescent lamp has a temperature of 2000k. calculate the fraction of radiation emitted in the visible light band if the filament is approximated as blackbody

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]
