Calorimeters are devices that are commonly used to measure the heating value of fuels. For example, a Junker's flow calorimeter is used to measure the heating value of gaseous fuels. A bomb calorimeter, on the other hand, is used to measure the heating value of liquid or solid fuels, such as kerosene, heating oil, or coal. Perform a search to obtain information about these two types of calorimeters. Write a brief report discussing the principles behind the operation of these calorimeters

Assume that gasoline is burned with 99% efficiency in a car engine, with 1% remaining unbumed in the exhaust gases as VOCs; If the engine exhausts 16 kg of gases (MW = 30) for each kg of gasoline (MW = 100), calculate the fraction of VOCs in the exhaust. Give your answer in parts per million.

Calculate the weight of 1m3 of kerosene if it has a mass of 855 kg. Provide answer in kN, to the nearest 100th. Your Answer:

! Required information Sometimes equations can be developed and practical problems solved by knowing nothing more than the dimensions of the key parameters. For example, consider the heat loss through a window in a building. Window efficiency is rated in terms of R value, which has the unit of ft2-hr-°F/Btu. A certain manufacturer offers a double-pane window with R=2.5 and also a triple-pane window with R= 3.4. Both windows are 3.5 ft by 5 ft. On a given winter day, the temperature difference between the inside and outside is 45°F. How much heat is lost through the double-pane window? Btu

If a gas has a pressure of 0.500 atmospheres, a volume of 25.0 L, and its temperature is 35 Celsius, how many moles of gas are there?

The figure shows a U-tube having a 5 mm x 5 mm square cross-section filled with mercury (specific gravity = 13.6) upto a height of 20 cm in each limb (open to the atmosphere). 50 cm Mercury 20 cm If 5 cm³ of water is added to the right limb, the new height (in cm up to two decimal places) of mercury in the LEFT limb will be

An observer is located at 35 degrees North latitude and wants to know the declination of something that just reached its maximum altitude 75 degrees above the southern horizon. What is the declination of that object? (Hint: Think about what declination is measured relative to before starting your calculations)

Consider a mercury manometer connected to a tank of water, as shown in the diagram below. Please calculate the ratio of hm to hw. (The specific gravity of mercury=13.56)

An observer is located at 65 degrees South latitude and wants to know the declination of something that just reached its maximum altitude 75 degrees above the southern horizon. What is the declination of that object? (Hint: Think about what declination is measured relative to before starting your calculations)

Mercury is often used in thermometers. The mercury sits in a bulb on the bottom of the thermometer and rises up a thin capillary tube as the temperature rises. Suppose a mercury thermometer contains 8,380g of mercury and has a capillary that is 0.400mm in diameter. How far does the mercury rise in the capillary when the temperature changes from 0.0 0C to 25.0 0C?
