You have just taken a job at Subs-R-Us submarine design and construction company and you are reviewing the design of a new submarine that will be used to watch fish underwater (so it needs windows). Your colleague has designed the windows on the submarine to withstand a pressure differential of 150 psi. Assuming a factor of safety of 3 in the design, what would you recommend as the maximum safe diving depth for the new submarine

What precautions should you take to prevent injuries when dealing with heavy loads?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Which of the following refers to refers to how well the control system responds to sudden changes in the system. a)-transient regulation b)- distributed regulation c)-constant regulation d)-steady-state regulation
