Fire safety

Fire safety is a new domain emerged in the early 90s to enable the design of buildings, structures, and infrastructure against destruction through fire. It also includes the provisions of building codes. This field is mostly associated with the design and efficient planning of a building, to reduce the destruction caused by fire. The branch of engineering that deals with it for the safety of the buildings from destruction of fire, is known as fire safety engineering.

Q1
a- A piston cylinder maintaining gas at 137kpa , 16°C, and the volume is
0.2 m3. The gas is compressed to 600 kpa, 260 °C. Calculate the heat
transfer during the process. Consider the process as a polytropic .R=
0.2081 [kJ/kg.K] ,CV= 0.3122kj/kg k.
b- Water in a chamber within which piston moves maintaining constant
pressure at 330 F, quality 85% with a volume of 0.12 m'. A heater is
turned on heating the water with 3 kw. What is the elapsed time to
vaporize all the liquid? h= 887,5 Btu/lbm ,v=0.01776 ft’/lbm
,Vg=4.29ft/lbm
