Sanew intern for the clothing bazaar, you are asked to look atthe appropriatelayeringof clothesto promote wearer comfort. you decide to useenergy loss through the cylindricalsleevesto analyze a number of options. using the layering configuration below, show how you will estimate whether the wearer will be too hot, too cold, or perfectly comfortable wearing these layers of clothes. assume that the steady state metabolic energy dissipation for the individual is 58.2 w/m

On a average work day more than work place firs are reorted

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
