Design a Process control system To maintain the Drum level in a steam boiler system. Feed water pumped into tank is used to regulate drum level Drum level range is - 10 inches to 10 inches. It is desire to maltain level at 0 (Zero) inch with high accuracy. Major disturbance in the system is frequent change in the load steam flow out from the drum) You have to select controller from the list below a) Two position differntial gap...
Fuel is burned in a boiler to produce saturated steam at 10.0 bar absolute pressure from saturated liquid water at 10.0 bar absolute pressure. This H20 flows through tubes that run through the boiler, Energy released by combustion is transferred as heat through the walls of the tubes to convert the liquid water to steam at 10.0 bar. The fuel consists of 37 mol% ethane and 63 mol% acetylene, and is fed in the vapor phase at 50 °C and...
Descriptive and Predictive. Describe each one. How are they different? How do they work together? Why are they both necessary? What is the biggest difference between the two?
1. Steam power plant (a) The boiler of a power plant operates at a maximum temperature of 750oC. The condenser of the power plant draws in cooling water at 20oC. What is the theoretical maximum efficiency of the plant? (b) Now suppose that a real power plant is built to have an efficiency that is 80% of the theoretical efficiency. The power plant needs to generate 1GW (giga-watt) of power. How much energy (per second) needs to be supplied by...
A boiler is at a pressure of 80 psia. Use steam tables for sea level. (i) At what temperature does the water boil?(ii) How much heat input ( in Btu/hr) is required to heat 20 pounds per hour of water from 70 F to this boiling point? (iii) How much heat input (in Btu/hr) is needed to convert 20 pounds per hour of water from 70 F into saturated steam at 80 psi pressure?( iv) How much heat input (in...

What is transpiration? how does it work, what is its function? What tissue accomplishes this? What is translocation? how does it work, what is its function? What tissue accomplishes this? Xylem/phloem function and structure. Tension/cohesion model of transpiration (capillary action/evaporation). Why does water get pulled upward? How do leaves function in transpiration? How stomata function in transpiration – why there were more stomata on the bottom of the leaf than on the top?
