Description

1.1. Assess the suitability of the shop (ie the respective needs and the actual air) capacity for work, during which the released CO, ethylene, ammonia, sulfur dioxide, as well as the Q J / h waste heat.
Initial data:
Volume management - V1 = 1600 m2
Secrete substances:
G1 = 98 g / hr (CO)
G2 = 2,3 g / h (ethylene)
G3 = 6 g / h (ammonia),
G4 = 55 g / Hr (sulfur dioxide)
Q 2 = 6,91 × 106 J / h (excessive heat).
K = 5 (Number of air)
The supply air temperature is 23 0C t1 =
The temperature in the working zone is t2 = 27 0C. Exhaust holes are located at a height of 5 meters from the work site.
PDKSO = 20 mg / m3;
PDKS2N2 = 1 mg / m3;
PDKNH3 = 20 mg / m3;
PDKSO2 = 10 mg / m3.

2.2 The challenge for the independent solutions.
To calculate the total artificial (fluorescent) lighting by utilization of light flux in the room
Initial data:
Room dimensions: length a = 5 m, width b = 4 m, height suspension lamp h = 3 m, the reflection coefficients of the walls and ceiling s = 50% = 70% p.
Safety factor K = 1.3.
Irregularity ratio Z = 1,1.
Number of lamps in the luminaire - 2. The length of the recommended series LSPO1 lamp, designed for two fluorescent lamps is equal to 1,536 m.
Rank visual work - IV - medium accuracy

Problem 3.2.1
Assess the conditions at the workplace noise.
Initial data:
Duration -8ch change.
t1 3,0
t2 1,0
t3 3,0
L1 90
L2 55
L3 90
L4 72

Problem 3.2.2
Calculate the level of noise intensity in an area where there are three non-directional source.
Initial data:
Lw1 45
Lw2 70
r1 4,0
r2 1,5
Humidity is 80%.

Problem 5.2.1.
Determine the effectiveness of the human dose
Initial data:
The irradiated organs - the gonads (sexual glands). Equivalent dose - q1 = 250 mSv.
The irradiated organs - intestines. Equivalent dose - q2 = 720 mSv.
