Answer:
The best way to ensure that OSHA will conduct a site inspection is by the submission a signed (by a current employee or employee representative) Formal Written complaints following OSHA guidelines (which can be found in the Council of Safety and Health (COSH) website) which will enable the commencement of process for an on site inspection
As such it is advisable to go through the following procedure before, filing a complaint
1) Talk to your workers union about the hazard
2) If you do not belong to a union, talk to your co-workers
3) Inform your employer who has responsibility for on the job safety
4) Speak or have a meeting with OSHA so as to receive guidance before filing a complaint
Explanation:
Answer:
(b) Constant (minimum) volume
Explanation:
In the idealized Otto cycle there are 4 process that are
- Reversible adiabatic compression
- Addition of heat at constant volume
- Reversible adiabatic expansion
- Rejection of constant volume
So from above discussion we can see that heat is added when there is constant (minimum) volume which is given in option (b) so option (b) will be the correct answer
Answer:
74.12kg/day
Explanation:
Equation of reaction for the neutralization reaction of sodium hydroxide and sulfuric acid: 2NaOH + H2SO4 yields Na2SO4 + 2H2O
Mass of sulfuric acid produced per day = 90,800kg
Percentage of sulfuric acid in wastewater = 0.1%
Mass of sulfuric acid that ends up in wastewater per day = 0.1/100 × 90,800 = 90.8kg
From the equation of reaction, 2 moles of NaOH (80kg of NaOH) is required to neutralize 1 mole of H2SO4 (98kg of H2SO4)
80kg of NaOH is required to neutralize 98kg of sulfuric acid
90.8kg of sulfuric acid would be neutralized by (90.8×80)/98kg of NaOH = 74.14kg/day of NaOH
