Many toilets in commercial establishments have a value printed on them stating the amount of water consumed per flush. For example, a label of 2 Lpf indicates the consumption of 2 liters per flush. If a toilet is rated at 3 Lpf, how many flushes are required to consume 20 gallons [gal] of water?

The door is 1.2 m high and I m wide, and the top edge of the door is 8 m below the free surface of the water. Determine the hydrostatic force on the er of the door, and discuss if 10 the masse door if it is located at the center o if the driver can open the door, if Answer the following statements by True or False: 1. Superchargers are used to increase the power of an IC engine by raising the intake pressure and thus allowing more fuel to be burned per cycle. 2. Scavenging is the process by which the oil rings scrape the lubricating oil from the cylinder wall and allow the oil to return to the oil pan. 3. The power output of a two-stroke engine equals that of a four-stroke engine for the same displacement. 4. After coolers are used after the compressor to drop the air temperature and thus increase its density. 5. The rotary…arrow_forwardAnswer the following statements by True or False: 1.

The power output of a two-stroke engine equals that of a four-stroke engine for the same displacement. 4. After coolers are used after the compressor to drop the air temperature and thus increase its density. 5. The rotary engine has the advantages of better sealing of high pressure gases and less wear on seals.arrow_forward

The belt suddenly starts in an upward direction so that slipping instantly occurs between the belt and the boxes. The kinetic friction coefficients between the belt and the boxes are μk,A = 0.3 and μk,B = 0.32. Determine the initial acceleration of each box. Will the blocks stay together, or separate? 80 lb 100 lb A B 15° Hint: to see if the boxes stay together or separate, first assume they separate, and see if their resulting motion (acceleration) validates that assumption. If the their motion is not consistent with the assumption of separation, then they must stay together.arrow_forward
- An ideal gas is enclosed in a cylinder which has a movable piston. The gas is heated, resulting in an increase in temperature of the gas, and work is done by the gas on the piston so that the pressure remains constant. a) Is the work done by the gas negative, positive or zero? b) From a microscopic view, how is the internal energy of the gas molecules affected? c) Is the heat less than, greater than or equal to the work? Explain you answer.arrow_forwardI need to adapt a real-life system to this assignment. It doesn't need to be a very complicated system. I am a senior mechanical engineering student.
