Chapter 55, Problem 4MC
All of the following are true statements about flushing an A/C system after a compressor failure, except
- The condenser must be flushed and the receiver/ dryer replaced.
- Filter screens are sometimes located in the suction side of the compressor and in the receiver/dryer. These screens confine foreign material to the compressor, condenser, receiver/dryer, and connecting hoses.
- Use only CFCs for flushing. After the system has been flushed, be sure to oil all components that require it.
- Some manufacturers recommend replacing the clogged components and installing a liquid line (inline) filter just ahead of the expansion valve or orifice tube instead of flushing the system.

1-While refilling an 8-quart (7.57 L) system with coolant: Technician A initially puts in 4 quarts (3.78 L) of straight coolant and tops it off with water. Technician B fills the system with the correct mixture, tightens the radiator cap, and then checks for leaks. Who is correct?
2-While checking for conditions that might cause coolant electrolysis: Technician A places the positive lead of a voltmeter into the coolant and connects the negative lead to a ground. Technician B checks for the presence of voltage in the coolant with the ignition off. Who is correct?
3-Technician A says that if the PCV valve or connecting hoses become clogged, excessive pressure will develop in the crankcase and can cause oil leaks. Technician B says that if the PCV valve or connecting hoses become clogged, oil may be pushed into the air cleaner or cause it to be drawn into the intake manifold. Who is correct?
4-While bleeding air from a cooling system: Technician A loosens a heater hose at its highest…

A 2 inch-diameter horizontal jet of water with a velocity of 20 ft/s relative to
the ground strikes a flat plate that is attached to a car moving at a velocity of
Ve. After it hits, the water splatters in all directions in the plane of the plate.
Investigate the effect of the car velocity V. on the force exerted on the plate.
