In a concentrated solar power plant, molten salt tank is used to store the thermal energy from the sun during the day. The tank wall thickness is 3cm containing molten salt at a temperature of 390 degree Celsius. There is atmospheric air outside the tank at a temperature of 30 degree Celsius. Suppose heat is lost as a result of heat transfer from the molten salt to the atmospheric air. What is the mode of heat transfer in this condition?

In some high-rise buildings, water is stored in an elevatedtank on the roof to minimize pressure fluctuations inthe system. Consider water that is pumped through a 10-cmsteel pipe to the roof of a 200-m-tall building; the pump ison the ground floor. For a water temperature of lOOC and aflow of 0.02 m3/s, what is the pressure at the pump discharge(in kPa)?
Most automobiles have a coolant reservoir to catch radiator fluid that may overflow when the engine is hot. Such a radiator, made of copper, is filled to its 12-L capacity when at 10.0°C. -What volume of radiator fluid, in liters, will overflow when the radiator and fluid reach their 99.5°C operating temperature, given that the fluid’s thermal coefficient of volume expansion is 400.0 × 10-6 / °C? The coefficient of volume expansion for copper is 5.1 × 10-5 /°C.
It is important for the body to be able to cool itself even duringmoderate exercise. Suppose a 70kg man runs on a treadmill for 30min and at a (total)metabolic energy expenditure rate of 1000W. Suppose also that the man cannot perspire; and cannot lose any heat viaconduction, convection and radiation (as would be the case with astronauts wearing theirair-tight spacesuit but w/o portable cooling unit). By how much would the man’s bodytemperature increase at the end of the 30min exercise? Express your answer in oC. A) 0.5B) 1.4C) 3.1D) 5.7E) 8.8
SUPPOSE THE AMBIENT TEMPERATURE IS 20degrees CELSIUS, AND THE HOT RESERVOIR CONSISTS OF A SPHERICAL TANK WITH A RADIUS OF 4.00 m, THAT ACTS AS AN IDEAL EMITTER OF RADIATION.

To ensure a tight fit, the aluminum rivet used in airplane construction are made slightly larger than the rivet holes and cooled by dry ice (solid CO2) before being driven. If the diameter of a hole is 0.500 cm, what should be the diameter of a rive at 20 degree Celsius if its diameter is equal that of a hole when the rivet is cooled to -78 degree Celsius, the temperature of dry ice? Assume the coefficient of expansion to remain constant. (Given and solutions)

A gasoline engine is at a location where the temperature is measured to be 14.2 °C and produces 347 KW at 5800 rpm while consuming 0.0184 kg's of fuel. During operation, data shows that its mechanical energy loss is 18 %, the actual volume of air going into each cylinder is 80% (the volumetric efficiency has a negligible variation), and the actual fuel-to-air ratio is 0.065. What were the engine parameters at sea level conditions if the pressure here is 100.3 kPa and the temeratur here is 18 Uc hotter than that of the alevated conditions? Determine at sea-level conditions the ISFC in ka/kW-hr Use four (4) decimal places in your solution and answer.
