Afurnace is used in conjunction with a boiler to generate steam and electricity. methane at 25°c is used as the fuel entering the furnace. air is also added at 10.0 % excess and preheated to 100°c. ninety percent of the methane fed is consumed, the product gas contains 10.0 mole co2/mol co, and the combustion products leave the furnace at 400°c. for a basis of 1,000 mol ch4 fed/s, 1) calculate the flowrates for inlet and outlet species and 2) set up the equations and indicate the steps required to calculate the heat transfer rate from the furnace (but do not complete calculations). indicate if the following changes will increase or decrease the rate of heat transfer (assume the fuel feed rate and the fractional conversion of methane remain constant). briefly explain your answers. () increasing the temperature of the inlet air, (ii) increasing the selectivity of co2 to co formation in the furnace.

2. you__turn left on a red light if you are in the left-most lane of a one-way street, you're turning into the left-most lane of a one-way street, and no nearby sign prohibits the turn.

Follow the steps provided in the simulation to add water to the graduated cylinder, select one of the three samples (copper, silver, or gold), set its mass to the values given in the statements below, and calculate its density. here is a summary of the steps required: add water by clicking and holding prepare a known volume of water button. until the desired volume of water has been added. if more than the desired volume is added, click the reset button. button and redo the procedure. a single click will add about 21.0 ml of water. to set the mass, click and hold weigh out metal button. until the desired amount of metal is added to the weighing pan. once the desired mass of the metal is added, release the button. transfer the metal to water and then click on calculate density button. to see how the density is calculated using water displacement to measure the volume of the solid. to save time you can approximate the initial volume of water to â±1 ml and the initial mass of the solid to â±1 g. for example, if you are asked to add 23 ml of water, add between 22 ml and 24 ml. which metals in each of the following sets will have equal density? check all that apply.
