Q 1. VENTILATION SURVEYS
A pressure quantity survey is being undertaken in an access decline used as an intake airway to an underground mine. The survey uses both traverse barometer and trailing hose methods.
The decline is 250 m deep and 2,500m long with an excavation profile 5 m wide and 5 m high. The total resistance of the decline is 0.0229Ns2/m8
Barometric pressure on surface = 99.550 kPa
Average air density in the decline = 1.18 kg/m3
Air velocity in decline = 4.8 m/s
Trailing hose is 250 m long with pressure measurements made using an inclined manometer graduated in mm H20.
v. What would the trailing hose manometer reading be, in mm H20, when used in this decline ?
The car's position is defined by the position vector, where . The image below shows the system projected onto the x-y plane. What are the car's velocity and acceleration vectors at this position
In an undisturbed soil formation, it is known that the dry soil weight is 115pcf. The specific gravity of the soil particle is 2.75.a) What is the saturation wet unit weight of the soil b) What is the submerged weight of the soil
A concrete building has floor area 10 m by 20 m and is 4 m high. THe building has four windows with a height 1.6 m and a width 2 m. After 10 minutes gases in the room have an average temperature of 700 degree Celcius.
calculate the depth of water in a stormwater pond resulting from a two hour rainfall event. the rainfall occurs over a 24-acre watershed at an average rate of 1 inch/hour. the runoff coefficient is 0.5.
