For an automotive spark-ignition engine, the combustion duration (from time of ignition through completion) is approximately one

-sixth of a crankshaft revolution. This corresponds to a time of approximately 17 ms at an engine speed of 600 rev/min. To maintain the same combustion duration of one-sixth of a crankshaft revolution at 3,000 rev/min, turbulence must increase the mass rate of conversion of reactants to products by a factor of _________ compared the rate of conversion at 600 rev/min.

Answer:

1.72

Explanation:

Given that:

Engine speed = 600 rev/min

Crankshaft speed = 3000 rev/min

The mass rate must increase by a factor of 1.72 compared to the rate of conversion at 600 rev/min

A power cycle under development has two options for a condenser. One outputs saturated water and one outputs saturated vapor. Th
agasfer [191]

Answer:

408 J/kg

662696.7 J/kg

Explanation:

Workdone by compression process in a pump can be isothermally expressed as :

W = P_1V_1 \ In \frac{P_2}{P_1}

For water at inlet pressure 1. 0 bar;

the specific values for :

saturated vapor v_g = 1.694 m^2 kg

saturated liquid v_f = 0.001043 \  m^2 kg

∴ we have

P_1 = 1.0 bar = 1. 0 × 10⁵ N/m²

P_2 = 50 bar = 50  × 10⁵ N/m²

For saturated water output from condenser work; we have

W = P_1V_f \ In (\frac{P_2}{P_1})

W = (1.0*10^{-5})(0.001043) In ( \frac{50}{10} ) J/kg

W = 408 J/kg

For saturated vapor output from condenser

Work required :

W = P_1V_g \ In ( \frac{P_2}{P_1} )

W = 1.0*10^5*1.694 \ In ( \frac{50}{1.0}) J/kg

W = 662696.7 J/kg

When storing used oil, it needs to be kept in ___________ containers. A) MetalB) PlasticC) UncoveredD) Leakproof
Romashka-Z-Leto [24]

Answer:

D. Leak-proof

Explanation:

Used oils are required to be stored in closed containers or tanks which will remain closed when oil is not added or removed. Alternatively, used oils can be stored in containers labeled "Used Oil"  for regulated hazardous waste storing. A leak-proof container is one that has no drips and dribbles when the container lid is closed. These containers should be kept in good conditions away from rusting, leaks or deteriorations. It is important to mention that used oil should not be stored in anything apart from tanks and leak-proof storage containers.
