- Unreasonable Results - A slightly deranged Arctic inventor surrounded by ice thinks it would be much less mechanically complex to cool a car engine by melting ice on it than by having a water-cooled system with a radiator, water pump, antifreeze, and so on. (a) If 80% of the energy in 1.00 gal of gasoline is converted into “waste heat” in a car engine, how many kilograms of 0C ice could it melt? (b) Is this a reasonable amount of ice to carry around to cool the engine for 1.00 gal of gasoline consumption? (c) What premises or assumptions are unreasonable?A ship displaces 7500cu.m of seawater with RD 1.025. what is its new displacement if its floating atthe same draft in water with RD 1.015?A brand-new pick-up truck was driven and tested on a national highway. Due to a very light traffic, 8hp is highly required to drive the said vehicle with a mass of 1800kg at a speed rate of 60kph. Consider the friction and air resistance. a) How much power is needed in order to drive the truck at a same rate up a 10% grade (a hill rising 10m vertically in 100m horizontally)? (in hp)b) Meanwhile, how much power is required for the truck still at a same rate down a 1% grade? (in hp)

Location A has a constant wind velocity of 10 m/s, while Location B has a wind velocity of 5 m/s for 12 hours per day and a wind velocity of 15 m/s for 12 hours per day. Compare the total energy produced per day for identical wind turbines at the two locations. The energy is given by the formula E = 0.5*(air density)*(efficiency)*velocity^3*(Turbine area)*time. Keep the answer in terms of (efficiency)*(Area). **Also is v average velocity or regular, non-average velocity?***Consider an automobile with a mass of 5500 lbm braking to a stop from a speed of 55 miles/h.(a) How much energy (Btu) is dissipated as heat by the friction of the braking process?(b) Suppose that throughout the United States, 300,000,000 such braking processes occur in the course of a given day. Calculate the average rate (megawatts) at which energy is being dissipated by the resulting friction.(c) Find a source of information on the average per-capita consumption of electricity (kW) in the United States, France, and India. Roughly how many people in each country would have their electricity needs met if the braking energy calculated in Part (b) could be recovered and used to provide electricity?

A larger pump is to be designed based from the existing one to be used for pumping slurry (ρ = 1220 kg/m3) such that its best efficiency point occurs as close as possible to a volume flow rate of 48 gpm and at a net head of 15 ft. Calculate the new pump diameter in inches.
