Shipra Manufacturing Company is thinking about development of a strong charge producing measure by adding one-ton limit during heaters. Each clump (one ton) of charge should go through 30 minutes of heater time, including stack and dump tasks. In any case, the heater potential use factor is just 80% because of stream limitations in different pieces of the framework. Required yield for the new design is to be 16 tons for each shift (8 hours). Plant (framework) proficiency is assessed at 50% of limit. (a) Determine the quantity of heaters required. (b) Estimate the percent of time the heaters will be inactive.

QUESTION 3 A Type I offshore life jacket (i.e. personal flotation device) is the type worn by commercial fishermen - it is designed for extended survival in rough, open seawater. Consider such a life jacket that uses an impermeable foam material with a density of 32 kg/m³ - the other parts of the life jacket (straps, fasteners, etc) weigh 0.6 kg and are of negligible volume to the design. a) Draw a free body force diagram for the life jacket. b) Determine the minimum volume of foam material (in L) that is needed for the life jacket in order to provide a minimum 98 N net upward force when it is fully submerged in seawater (as required by US Coast Guard regulations).
