Figure 1.1. shows a simplified diagram of the camping stove used by a famous scientist up a mountain, in which gas under pressure is transported to the four nozzles via metal piping. A valve is used to control the flowrate by reducing the delivery pressure to a maximum of 2 kPa gauge. The diameter of each nozzle is 1 mm. The density of camping gas at atmospheric pressure is 2.686 kg m–3, and its calorific value on combustion is 126000 kJ m–3. Ignoring friction losses and making other appropriate assumptions, estimate the maximum volumetric flowrate of gas through the four nozzles if the valve is fully open, and hence the maximum rate of supply of heat.
I am really not sure how to do this question, am I suppose to use bernoulli's equation? What about height? Do I make an assumption on that?
any help appreciated.
