Using the method of Shokri and Beyler, calculate the radiant heat flux from a 10 ft diameter pool fire to a wall that is 15 ft away from the edge of the fire. Calculate the time it would take for someone to feel pain if they were being subjected to 3 kW/m2.
Please provide a step by step solution as soon as possible.
Shokri and Beyler method :
Radiant heat flux q" = 15.4(L/D)-1.59( kW/m2)
Where L is the distance from the edge of the fire.
D is the diameter of the pool fire.
Step1: written all data what is given.
Diameter of pool fire D = 10 ft
Distance from the edge of the fire L = 15 ft away
Step2: put all datas into the formula by using unit consistency and convert all the units in M.K.S system.
D = 10 ft * (0.305m/1 ft) = 3.05 m
L = 15 ft*(0.305 m/1ft) = 4.575 m
Heat flux,
q" = 15.4*(4.575/3.05)-1.59 = 8.08 kW/m2
Time required for someone to feel pain,
t = n*(35/qr")1.33
n is the safety factor,
n = 1/2 , if qr"=< 6 kW/m2
n = 1/4 if qr"> 6 kW/m2
Here qr"= 3 kW/m2
Then, n = 1/2
t = 1/2 *(35/3)1.33 = 13.12 s
Ans: time required for someone to feel pain t = 13.12 s
radiative heat flux q" = 8.08 kW/m2

1. (10) A door is receiving a constant heat flux of 10 kW/m2 from a fire in a room. The other side of the door is cooled by convection to air with T 25 C with a heat trans fer coefficient of 30 W/m2-C. The door is made of oak and is 4 cm thick. Use the 1-D heat equation to find the temperature distribution in the door. (Hint: you need to integrate the Heat Equation and then apply the...
When using the apparatus from this experiment, the average heat flux at the heater surface is calculated to be 7.2 kW/m2 and the temperature difference between the heater surface and freestream fluid temperature is 70°C. Calculate the Nusselt number (assume thermal conductivity of air = 0.02587 W/m-K). Answer: 62.82
Please answer question 2. Quastion 1 answer is already provided in the photos. 1. At an outdoor lot, there is a black-colored solar heat collection copper pipe. It is 50 meters long, 10 cm in inner diameter and 10.2 cm in outer diameter. The pipe is set horizontally. Assume that solar radiation in 1.0 kW/m2 shines on the entire surface of the pipe and convert 90% of the solar energy on the pipe into heat. There is water in 25...

Learn to apply your ethical values using the Giving Voice to Value (GVV) method. There are multiple GVV documents in this Module. Review them all. You may do the exercises suggested in the documents but you do not have to post them in Canvas. You will learn how to factor your personal values into your ethical decisions from the method, you will still use the IDEA case analysis method when analyzing the GVV case, The Client Who Fell Through The...
