Let y be the height of the coffee in the funnel at any given time, so that just before the dripping starts we have y = 3. Since the coffee is draining out of the funnel, dy dt will be negative. What (approximately) will be the value of y when dy dt is at its smallest (closest to zero)?

Gather reliable information to brent make his decision. to gather this information, use newspapers, call insurance companies or look at their web sites, and review consumer magazines and web sites. also, look at the manufacturer web site or for information about gas mileage. list the sources you use and take notes.

Air enters a gas turbine with two stages of compression and two stages of expansion at 100 kpa and 17°c. this system uses a regenerator as well as reheating and intercooling – the intercooler returns the air to the inlet temperature. the pressure ratio across each compressor is 4 ; 300 kj/kg of heat are added to the air in each combustion chamber; and the regenerator operates perfectly while increasing the temperature of the cold air by 20°c. determine the system’s thermal efficiency. assume isentropic operations for all compressor and the turbine stages and use constant specific heats at room temperature.

The direction of the current in an alternating current circuit remains constant. is direct. changes repeatedly. changes randomly.
