When scientists and engineers develop solutions to problems, they use a series of steps that are part of the engineering design process. One version of the process is shown in this flowchart. Drag the correct option into each box to complete the flow chart. Identify a Need → ( ) → ( )→Choose a Solution to Test→Design a Prototype→( ) → ( ) →Redesign as Needed→Implement the Solution

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.
