4. A tank is initially filled with 300 gallon of salt solution containing 1 kg of salt per gallon. A brine containing 3 kg of salt per gallon runs into the tank at the rate of 10 gallons/minute, and the mixture, assumed to be kept uniform by stirring, runs out at the same rate. Find the amount of salt in the tank at any time t, and determine how long it will take for this amount to reach 500 kg.

SHOW COMPLETE SOLUTION An elevator is designed to transport 120 passengers per hour from the 1st floor to the 10th floor. The average mass of a passenger is 75kg and the average speed of the elevator is 130kph. Determine: A. The required capacity of the motor if the mechanical efficiency is 90% and if a 250 percent overload is allowed. B. The average power required
Consider a gravity-driven LED bulb that provides 16 lumens of lighting. The device uses a 10-kg sandbag that is raised by human power to a 2-m height. For continuous lighting, the bag needs to be raised every 20 minutes. Using an efficacy of 150 lumens per watt for the LED bulb, determine (a) the velocity of the sandbag as it descends and (b) the overall efficiency of the device.
We have already noted two sources of systematic error in the use of this method: not enough sample to displace all the air from the flask and the finite vapor pressure of the unknown. Consider the following possible errors. For each one, describe how the results might be impacted. Please try to be specific (e.g. “The molar mass will be overestimated because…”) The volume of your flask was found by weighing it, filled with water, at room temperature (20ºC). At 100ºC, because of the expansion of glass, the volume is slightly greater. How could this affect your results? We have assumed that the temperature of the vapor is the same as the temperature of the boiling water. What if this were not correct? What could be the impact if some of the vapor leaks before all of it can be condensed?

1 - A square chip, with side ? = 5 mm, operates under isothermal conditions.The chip is positioned on a substrate so that its side and bottom surfaces are thermally insulated, while its top surface is exposed to theflow of a refrigerant at ?∞ = 15°C. From reliability considerations, the chip temperature cannot exceed ? = 85°C. The refrigerant being air, with a convection heat transfer coefficientcorresponding ℎ = 200 W/(m2K), what is the maximum allowable power for the chip? Since the coolant is a dielectric liquid for which ℎ = 3000 W/(m2K), what is the maximum allowed power?
