errors in engineering design are unavoidable. the nonscientific component design is primary. mathematics is a necessary part of the study of design. design courses form a part of engineering curricula.

The diesel oil must never be allowed to mix with the heavy fuel The temperature of the fuel from the pre –heater should be gradually reduced afterswitching over the three –way valve The heating steam to the pre-heater should be secured as soon as the diesel fuel passesthrough the three-way valve The heating steam must be secured before the diesel oil passes through the three-wayvalve
