I need help with the second table. and these questions   1- If 1 gallon of oil = 1.4 therm, how many gallons have been wasted by heat loss in Feb? (1 therm = 100,000 BTU)   2- If $1.30 per therm, how much did you waste from house heat loss in Feb?

Please help and show work.

Problem 3: Insulation To=1 Toowwww Steam Tx2 T₂ T3 www www R₁ R₁ R₂ www.T R₂ Steam at T1 = 320 °C flows in a cast iron pipe (k= 80 W/m. °C) whose inner and outer diameters are 5 cm = 0.05 m and D₂ = 5.5 cm = 0.055 m, respectively. The pipe is covered with 3-cm-thick glass wool insulation with k = 0.05 W/m. °C. Heat is lost to surroundings at T2 = 5 °C by natural convection and radiation, with a combined heat transfer coefficient of h₂ = 18 W/m². °C. Taking the heat transfer coefficient inside the pipe to be h₁ = 60 W/m². °C, determine the temperature drops across the pipe and the insulation. The determination is based on a unit length of the pipe (L = 1 m). Assumptions 1. Heat transfer is one-dimensional since there is no indication of any change with time. 2. Heat transfer is one-dimensional since there is thermal symmetry about the centreline and no variation in the axial direction. 3. Thermal conductivities are constant. 4. The thermal contact resistant at the interface is…

Why will more heat be lost by the hot water than gained by the cold water?   a)Calorimeter will absorb some of the heat. (Always the same amount.)   b)Calorimeter will absorb some of the heat. (The greater the ΔT, the more of it will be absorbed by the calorimeter.)   c)Conservation of energy does not work in calorimeters.   d)We are using different amounts of hot and cold water.

Please help!!! (Will provide helpful ratings for correct solution)

Topic: Population Growth   A team of biologists performed an experiment to determine the effectiveness of a chemical to accelerate the growth of a specific bacterium. They introduce 40 bacterial colonies into a growth medium and exactly two hours later, the number of colonies has grown to 200. In fact, the number of colonies grows exponentially for the first five hours of the experiment. Calculate the number of colonies that were present five hours after the experiment began. (Use ??/?? = ??)

reply to the jobsite owner effectivlr and clearl   I would like to explore the possibility of using a lighting control system. There are times when office staff works long hours and researchers sometimes need to be in the building on nights and weekends. Often times they leave the lights on which increases my electricity costs. I would like to be able to program the lights on a schedule and if the staff needs to work outside that schedule they could request a change with our maintenance staff ahead of time. Could you please look into this and provide me with some potential options.  Regards-Owner

ready to move. Pick a mass of the object and one type of surface and record them. Mass (M) Surface type = kg, . Then click to start and keep observing force applied in lab quest. When object shows a kink means ready to move, check value of force, that is the force when it is equal to static friction force. It is the maximum value of force that appears in the screen and graph as maximum value of force. Record its value from graph. Fs (static max) = _ N Keep looking the lab quest and see when the value of force drops from its maximum value,

Tire manufacturers recommend that you check your tire pressure monthly to avoid unnecessary tire wear and enhance safety. This is best done when the tires are cold meaning; the car has not been driven for at least 2 hours. Since you leave for work before the sun comes up you decide to inflate your tires to the recommended pressure right after you get home from work in the afternoon when the tires are still warm. What would you find if you rechecked your tire pressure after the tires have cooled down? A.Tire pressure has decreased because there is a decrease in kinetic energy of themolecules resulting in more collisions with the inside walls of the tire thusincreasing the pressure inside the tire. B.Tire pressure has increased because there is a decrease in kinetic energy of the molecules resulting in fewer collisions with the inside walls of the tire thus decreasing the pressure inside the tire. C.Tire pressure has increased because there is an increase in kinetic energy of the…
