Corrosion control methods

Corrosion may be defined as the method in which metals are attacked on their exteriors by gases existing in the atmosphere, converting them to their oxides, nitrides, sulfides, etc.

Application: Assume a small spacecraft is in open space. One panel is a dedicated radiator (dimensions in image) and is painted with S13 GLO white paint (emissivity = .89). If the radiator is at 30C and has a full view factor to space, how much heat can it reject from the system? (How much is this radiator radiating to space?). Use 3K for space temperature. Round answer up to one decimal place. No need to include units. (Remember that -/+ signs are used in respect to direction of energy transfer) h 37°F Cloudy HD GAN .1 m Radiator .3 m Q Search
QUESTION 9 A manufacturing factory located at 30° N latitude has a window area 35 m² that consists of double- pane windows made of clear glass (SHGC = 0.766) as given in the Figure Q2. To reduce the solar heat gain on a hot day, a reflective film that reduce the SGHC to 0.261 is considered. The building need cooling during the months of June, July, August and September and need heating during the months of October through April. The average daily solar heat fluxes incident on the west side of this latitude is given in the Table Q2 below. The unit cost of electricity and the natural gas are RM 0.30/kWh and RM1.75/therm, respectively. If the coefficient of performance of the cooling system is 3.0 and the efficiency of the furnace is 0.80. Determine: i. the net annual cost savings due to installing reflective coating on the windows ii. the simple payback period if the installation cost of the reflective film is RM 70/m² Glass Solar Radiation Reflective film KAir space Reflected…
please answer it correctly stepwise. will give you thumbsup. this is a complete question. you just have to find view factors or shape factors of this figure
The last portion asks you for "net radiant heat flux to the surface", meaning that positive net radiative heat flux means in and negative net radiative heat flux means out. This is opposite the typical sign convention - be aware of this

These images show one of the large `VLT’ telescopes at the European Southern Observatory’s facility at Cerro Paranal, Chile. The place where the laser beam comes out (seen in the inset photo) is just out of sight off of the top edge of the large photo. Also note that if you look down the telescope tube (in the main photo), you can see the tube’s front-end structure. Why is there a laser beam shooting out of the front of this telescope (in the inset picture)? Group of answer choices The beam creates an `artificial star’, which is used by an adaptive-optics system to measure (and counteract) the blurring effect of Earth’s atmosphere. The astronomers are bouncing light off of objects near the center of the Milky Way galaxy, to measure their distances from Earth. The astronomers are taking pictures of the surface of a planet (most likely Mars), and the laser allows them to light up the planet’s surface with a very specific color of light. The astronomers are engaged in the opening…
