Finishing Operations

Finishing operations are the processes that are applied to the workpiece at the end of a manufacturing process, and after completing all other relevant operations that bring the product to its required dimensions. Finishing operations involve polishing, reducing the surface roughness, eliminating wrinkling, and grinding to enhance the surface texture and provide a better surface finish to the workpiece surface.

A well-mixed, insulated water storage tank is to be maintained at internal temperature 60°C. The environmental temperature around the tank varies from -25°C to 30°C. The tank's exterior surfaces (total = 125 m²) have four different levels of insulation as indicated in the table. Surface Component Area, Effective RSI, 2 2 m². °C/W m² Surface A 60.0 Surface B 30.0 Surface C 30.0 Surface D 5.0 Say that just one surface can be selected to have its insulation upgraded such that its effective RSI would be doubled. Which should be selected to achieve the greatest reduction in heat loss? 10.0 15.0 4.0 0.5
An electrostatic precipitator (ESP) is installed to remove dust from the smoke with an efficiency of 95%. The migration velocity of dust particles is 30 cm/s and the smoke flow rate is 50 m³/s. Each collector plate has total area on both sides as 50 m². Which of the following statements is/are correct about the given ESP? A Total plate area required is approximately 500 m². B A total of 10 plates will suffice. C If efficiency is to be increased by 3%, total plate area will have to be increased by 152 m². D If the ESPs are placed in series each having 95% efficiency, then the number of ESPs required to achieve a minimum 99.5% efficiency is 3.

1. I have taken a sound reading and my sound level meter (SLM) is showing the result in Pascals, not dB (shouldn't have bought a cheap one). The maximum pressure shown is 101,008 Pa. Before the noise started, the air pressure was about 101,001 Pa, so the noise increased it by just 7 Pa. This doesn't seem right because the noise was really loud. Is my meter broken? What is the noise level in decibels (WRT 20µPa)?

Solve for what is being required. Room dimensions are: LxWxH = 8.50 m, 5.0 m, 3m. Originally, the room had linoleum flooring with an absorption coefficient of 0.03. Two opposite walls were cladded with unglazed bricks with an absorption coefficient of 0.02, the one having the entrance gypsum door (2.1 m X 0.80 m) with 0.05 abs.co.; the other two were just bare concrete with sliding glass window openings of 1.80m x 1.20 m each; the bare concrete with an abs.co. Of 0.31 and the window glass with 0.18, the ceiling, too , had bare concrete as its finish at 500 Hz. The client would like to renovate the space into an acoustical studio room and would like to change the ceiling and the flooring. The ceiling will have a vinyl faced fiberglass panel with an abs.co. of 0.71, and the floor will have mineral fiber tiles with an abs.co. Of 0.66, all at 500 Hz.
Which statement is TRUE about displacement ventilation in UFAD systems? air from the floor is prone to carrying dust vertical airflow may have health benefits mixing is enhanced resulting in even air temperatures supply air temperatures are lower than for overhead systems
