Water is to be heated from 15°C to 65°C as it flows through a 3-cm-internal-diameter 5-m-long tube. The tube is equipped with an electric resistance heater that provides uniform heating throughout the surface of the tube. The outer surface of the heater is well insulated, so in steady operation, all the heat generated in the heater is transferred to the water in the tube. If the system is to provide hot water at a rate of 10 L/min, determine the power rating of the resistance heater. Also estimate the inner surface temperature of the tube at the exit

A cube is being cooled within a tube that has air being pushed by a fan. The heat transfer coefficient (h) for the cube is lower when it is at the center of the tube, and higher when it is at the edges (resulting in a concave up parabola when it is plotted against the position). Why does this occur?
A long counter-flow heat exchanger cools water from 40°C to 10°C by passing the water via the inner tube through an enclosure of cold fluid. The water is flowing through a 3-cm diameter tube at a rate of 0.27 kg/s. The cold fluid enters the enclosure at −10°C and has a convection coefficient of 1200 W/m².K. The mass flow rate of the cold fluid and its specific heat are 1.2 kg/s and 1340 J/kg-K, respectively. (a) Assuming the flow is fully developed, find out the convection coefficient of the water flow. (b) What is the length of the heat exchanger? 1554 W/m²K 2 21.9m Water Cold Fluid
Consider a stainless steel spoon ( k = 8.7 Btu/hrft°F) partially immersed in boiling water at 200 deg * F in a kitchen at 75°F. The handle of the spoon has a cross section of 0.08in * 0.5in and extends 7 inches into the air from the free surface of the water. If the heat transfer coefficient at the exposed surfaces of the spoon handle is 3 Btu/hrft²°F, determine the temperature of the tip of the spoon handle. Assume that the heat loss from the tip of the spoon is negligible.

A steam condenser operates at 61 cm of Hg vacuum. The steam enters the condenser with a moisture content of 87%. Cooling water is supplied to the condenser at a temperature of 20 C with a terminal difference of 5 C. The water velocity of water inside the tube is to be limited to 2.5 m/s when using 2.5 cm outside diameter tubes whose thickness is 1.75 mm. The overall heat transfer coefficient of the tubes could be approximated by the equation U = 1213.4(v1/2), W/(m2-C) where v is the water velocity in m/sec. Determine: 1. The required mass flow of cooling water, kg/s 2. The required capacity of the circulating pump, liter per second 3. The Logarithmic Mean Temperature Difference, C 4. The required Number of tubes 5. The required length of tubes, (m), and number of passes
A student living in a 4 - m 5 - m 3 - m dormitory room turns on her 100 - W fan before she leaves the room on a summer day, hoping that the room will be cooler when she comes back in the evening. Assuming all the windows are tightly closed and disregarding any heat transfer through the walls and the windows, determine the temperature in the room when she comes back 8 h later. Use specific heat values at room temperature, and assume the room to be at 100 kPa and 20 ° C in the morning when she leaves.
Q-2/ An office room has an area of 7*5 square meter and 4m height, this room is heated by the radiator of a steam-heating system. The steam radiator transfers heat at a rate of 10 MJ/h, while a 100-W fan is used to distribute the warm air in the room. During this process, the rate of heat loss from the room is estimated to be about 5 MJ/h. If the initial temperature of the room air is 15°C. Determine; how long it will take for the air temperature to rise to 25°C. Assume constant specific heats at room temperature and the parametric pressure is I bar.
It is proposed to cool oil in a counter-current, concentric tube heatexchanger composed of a thin-walled inner tube of 0.02 m diametercarrying oil and thin-walled, perfectly insulated outer tube of 0.05 mdiameter carrying water. The oil flow rate is 50.0 kg min-1 and it has to becooled from 90°C to 40°C using 60 kg min-1 water at 20°C. Determine the length required for the heat exchanger. Comment onthe practicality of this length.
student was asked to do an experiment on a refrigerator test kit during an undergraduate laboratory class in an engineering college. He conducted the experiment for a period of 30 minute and measured that the refrigerated space is maintained at -5°C, while the temperature of the laboratory is 20°C. According to his experiment, it has found that during the experiment the refrigerator draws 1 kWh of electrical energy and 40000 kJ of heat is removed from the refrigerated space. Do you think there is an error in his experiment?
