1- Select the Pump that has the lowest acceptable Head. Using performance curve for iron and bronze pumps series S (Figure 7-16) 3- Assuming the boiler in the above figure uses diesel as fuel (C.V. =39000KJ/Kg ). If the combustion efficiency is 80%. If we don't want to use a fan what is the smallest diameter for the chimney. Assume the chimney length is 15m, the head 10m, ambient temperature is 25C, temperature of the flue gases is 250C. Note: Assume the factor of safety in selecting the boiler is 10%. 1- Select the Pump that has the lowest acceptable Head.
