  1. Adrian is trying to heat up a sphere (radius = 0.05 m) of unknown material in a furnace. She wants to know how long it will take for the object to heat up to 300°C when moved from room temperature (25°C) to a 600°C furnace. Use the following information to determine the time (in minutes) it will take for the sphere to reach 300°C after transfer to the furnace.

    Make sure to show validation for any equations that you use.

Density of object = 7400 kg/m3

Specific heat capacity = 520 J/(kg*K)

Conductivity = 50 W/(m*K)

Heat Transfer Coefficient = 45 W/(m2*K)

hot fluid at 230°C flows through a 1-meter pipe of 0.02m outside radius and 0.015m inside radius. The thermal conductivity of the pipe is 0.5 W/m.k, and the heat transfer coefficient (hi) inside is 300 W/m2 K. The pipe is located in a room at 30°C, and the heat transfer coefficient (ho) at the outer surface is 10 W/m2 k. Calculate the temperature drop (∆T) across the pipe wall.

Q. Unsteady conduction A large steel plate 0.02 m thick leaves a heat treating furnace at 425 oC. And the plate is plunged into water (at 25 oC) and cooled from both sides. How long does it take for the maximum temperature to reach 65 oC? For steel plate: thermal conductivity, k=30 W/m·K, density ?=7600 kg/m3, heat capacity cp=700 J/kg·K. Heat transfer coefficients: h=6000 W/m2·K in water. Please use two methods to calculate this question: (1) Directly apply the exact...

Consider a cube of density, specific heat, and thermal conductivity of 2700 kg/m3, 0.896 kJ/kg-K, and 204 W/m-K, respectively. The cube is 5 cm in length, and is initially at a temperature of 20 oC. For t>0, two of the boundary surfaces are insulated, two are subjected to uniform heating at a rate of 10,000 W/m2, and two dissipate heat by convection to an ambient temperature of 20 oC, with a heat transfer coefficient of 50 W/m2-K. Assuming lumped capacitance...

A spherical object (50 cm diameter, c=0.46 kJ/kg*C, k = 42 W/m*C, density = 7800 kg/m3 ) is initially at a uniform temperature of 450 C. It is suddenly placed in a constant temperature environment of 100 C. The convection transfer coefficient is 500 W/m2*C. How long would it take for temperature in the center of the sphere to cool down to 150 C? Note: Bi for a sphere is (hD)/(6k).Suggestion: First calculate Biot number, then determine if T is...

The fluid in a heat exchanger in a process plant needs to be warmed up prior to having process startup. The shell side of the heat exchanger contains the process fluid (water) while the tube side is supplied with steam at 150°C to facilitate the heating. Assume the exterior is well insulated such that heat losses are negligible. a) Derive the ODE and analytically solve for the function that describes the temperature of the fluid in the heat exchanger with...
