Concept explainers
Fuel systems of modern cars are designed so thermal expansion of gasoline doesn’t result in wasteful and polluting fuel spills. As an engineer, you’re asked to specify the size of an expansion tank that will handle this overflow. You know that gasoline comes from its underground storage at 10°C, and your expansion tank must handle the expansion of a full 75-L gas tank when the gas reaches a hot summer day’s temperature of 35°C. How large an expansion lank do you specify?

- I'm confused about this problem. What equation would I use? A 60,000 L fuel tank is filled with gasoline on a -10°C day, then rolled into a storage shed where the temperature is 20°C. If the tank is not vented, what minimum volume needs to be left empty at filling time so that the tank doesn’t rupture as it warms?arrow_forwardA steel rod 30.0 m long, installed when the temperature was 10°C, is in a bridge that heats up to 40oC on a hot summer day. Steel's coefficient of linear expansion is 1.2 × 10-5 K-1. The bridge is built so the rod has an expansion space of 5 cm. Is this enough space? What is the increase in the length of the rod, in mm?arrow_forwardJill takes in 0.0140 mol of air in a single breath. The air is taken in at 20.0°C and exhaled at 35.0°C. Her respiration rate is (1.30x10^1) breaths per minute. At what average rate does heat leave her body due to the temperature increase of the air? Provide your answer to three significant figures. HINT: Use the molar specific heat at constant volume to find the heat loss, where Cv = 5R/2 (for an ideal diatomic gas).arrow_forward

Your client desires that the heating system be large enough to raise the water temperature from 20 to 30°C in 3 h. The rate of heat loss from the water to the air at the outdoor design conditions is determined to be 960 W/m2, and the heater must also be able to maintain the pool at 30°C at those conditions. Heat losses to the ground are expected to be small and can be disregarded. The heater considered is a natural gas furnace whose efficiency is 80 percent. What heater size (in kW input) would you recommend to your client?arrow_forward
- Most cars have a coolant reservoir to catch radiator fluid that may overflow when the engine is hot. A radiator is made of copper and is filled to its 16.0-L capacity when at 10.0 °C. What volume of radiator fluid will overflow when the radiator and fluid reach a temperature of 95.0 °C, given that the fluid's volume coefficient of expansion is B=400×10/°C? (Your answer will be a conservative estimate, as most car radiators have operating temperatures greater than 95.0 °C).

Suppose you develop a new material for making pipes and turbines, which allows the maximum steam temperature to be raised to 600°C. Roughly how much money can you make in a year by installing your improved hardware, if you sell the additional electricity for 5 cents per kilowatt-hour?
