Answer:

winter viscosity grades

Explanation:

The “W”/winter viscosity grades describe the oil's viscosity under cold temperature engine starting conditions. There's a Low Temperature Cranking Viscosity which sets a viscosity requirement at various low temperatures to ensure that the oil isn't too thick so that the starter motor can't crank the engine over.

Answer:

Attached is the complete question but the weight of the mailbox and cross bar differs from the given values which are : weight of mail box = 3.2 Ib, weight of the uniform cross member = 10.3 Ib

Answer : moment of inertia = 186.7 Ib - in

Explanation:

Given data

weight of the mailbox = 3.2 Ib

weight of the uniform cross member = 10.3 Ib

The origin is of mailbox and cross member is 0

The perpendicular distance from Y axis of centroid of the mailbox

= 4 + (25/2) = 16.5"

The centroid of the bar =( ( 1 + 25 + 4 + 4 ) / 2 ) - 4  = 13"

therefore The moment of Inertia( Mo) = (3.2 * 16.5) + ( 10.3 * 13)

                                     = 52.8 + 133.9 = 186.7 Ib-in

The combined moment about O due to the weight of the mailbox and the cross member AB is; M_o = 122.4 lb.in (ccw)

We are given;

Weight of mailbox; W_m = 3.2 lb

Weight of uniform cross member; W_c = 10.3 lb

Now, from the attached diagram, let us calculate the geometric location of the mailbox and uniform cross section from point O.

Geometric location of mailbox from point O; g_m = 3 + (19/2) = 12.5 in

Geometric location of cross member from point O;

g_c = (¹/₂(1 + 19 + 3 + 7)) - 7

g_c = 8 in

Thus. combined moment about point O is;

M_o = (W_m × g_m) + (W_c × g_c)

M_o = (3.2 × 12.5) + (10.3 × 8)

M_o = 122.4 lb.in

Since positive then it is counterclockwise. Thus;

M_o = 122.4 lb.in (ccw)

b) the rate of entropy generation in the system's universe = ds/dt = 0.2603 KW/K

Explanation:

a) In steady state  

Net rate of Heat transfer = net rate of heat gain -  net rate of heat lost  

Hence, the rate of heat transfer = 0

b) In steady state, entropy generated  

ds/dt = - [ Qgain/Th1 + Qgain/Th2 - Qlost/300 K]

Substituting the given values, we get –  

ds/dt = -[5/1500 + 3/1000 – (5+3)/300]

ds/dt = - [0.0033 + 0.003 -0.2666]

ds/dt = 0.2603 KW/K

An environmental hazard is a substance, state or event which has the potential to threaten the surrounding natural environment and/or adversely affect human's health. This term incorporates topics like pollution, natural disasters and human-made hazards. Health studies investigate the human health effects of exposure to environmental hazards ranging from chemical pollutants to natural, technological or terrorist disasters. The environment in which we live can be considered as having three fundamental sets of components, physical, chemical, biological. Associations between an exposure and an adverse health effect do not, on their own, prove that the former is the cause of the latter. Many other non-causal associations could explain the findings. Physical hazards involve environmental hazards that can cause harm with or without contact. Examples are earthquakes, electromagnetic fields, floods, light pollution, noise pollution, vibration, x-rays etc. Radioactivity is associated with an exposure dependent risk of some cancers notably leukaemia. The scientific evidence of adverse health effects from general environmental exposure to these fields is "not proven". If there are adverse effects yet to be proven, the risk is probably likely to be small. Chemical substances cause significant damage to the environment. Tobacco smoke is the single biggest known airborne chemical risk to health, whether measured in terms of death rates or ill-health. To a much lesser degree of risk, these adverse effects apply to non-smokers exposed passively to sidestream tobacco smoke. Health effects of concern are asthma, bronchitis, lung cancer and similar lung diseases, and there is good evidence relating an increased risk of symptoms of these diseases with increasing concentration of Sulphur dioxide, ozone and other pollutants. Biohazards generally fall into two broad categories: those which produce adverse health effects through infection (microorganisms, viruses or toxins) and those which produce adverse effects in non-infective (allergic) ways.

Explanation:

A caisson is a watertight enclosure that can be pumped dry so that construction activities, such as the construction of piers can take place. A caisson is a watertight structure or chamber, usually made of wood, metal, or concrete, that is sunk to the bed of a river, lake, or ocean to provide a foundation or support for a bridge, building, or other structure.

A caisson is constructed onshore and then floated to the location where it is to be sunk into the water. Once in place, water is pumped out of the caisson, and construction workers enter the dry chamber to begin work on the foundation or support structure. The use of caissons has been an important development in the construction of bridges and other structures in areas with deep water or unstable soils.

A foundation called a caisson is used in construction on soft or deep water. It involves filling a series of large, watertight cylinders with concrete and sinking them into the ground. The base serves as a solid foundation for any subsequent structures. The construction of large structures like bridges, docks, and caissons is common.

Explanation:

This question is not complete, the complete question is;

The stagnation chamber of a wind tunnel is connected to a high-pressure air bottle farm which is outside the laboratory building. The two are connected by a long pipe of 4-in inside diameter. If the static pressure ratio between the bottle farm and the stagnation chamber is 10, and the bottle-farm static pressure is 100 atm, how long can the pipe be without choking? Assume adiabatic, subsonic, one-dimensional flow with a friction coefficient of 0.005

Answer:

the length of the pipe is 11583 in or 965.25 ft

Explanation:

Given the data in the question;

Static pressure ratio; p1/p2 = 10

friction coefficient f = 0.005

diameter of pipe, D =4 inch

first we obtain the value from FANN0 FLOW TABLE for pressure ratio of ( p1/p2 = 10 )so

4fL\(_{max}\) / D = 57.915

we substitute

(4×0.005×L\(_{max}\)) / 4  = 57.915

0.005L\(_{max}\) = 57.915

L\(_{max}\) = 57.915 / 0.005

L\(_{max}\)  = 11583 in

Therefore, the length of the pipe is 11583 in or 965.25 ft

Hot combustion gases, modeled as air behaving as an ideal gas, enter a steady-state turbine at 145 psi, 2700oR, and exit at 29 psi and 1974oR. The power output is 74.26 hp, and heat transfer from the turbine to the surroundings occurs at a rate of 14 BTU/s.

Required:

a)Determine the power output of the turbine, in hp.

b) The Flow rate

Answer:

a) \(w=74.26hp\)

b) \(m=0.22\)

Explanation:

From the question we are told that:

Initial Pressure \(p_1= 145 psi\)

Initial Temperature \(T_1 =2700oR=>2240.33^oF\)

Final Pressure \(p_2= 29 psi\)

Final Temperature \(t_2=1974oR=>1514.33^oF\)

Output Power \(w=74.26hp\)

Heat transfer Rate \(Q=14BTU/s\)

Generally the equation for Steady flow energy is mathematically given by

 \(Q-w=m(h_2-h_1)\)

Where

 \(m=Flow\ rate\)

From Steam table

 \(h_1=704btu/ib (at\ p_1= 145\ psi,\ T_1 =2700oR=>2240.33^oF )\)

 \(h_2=401btu/ib (at\ p_2= 29psi\ t_2=1974oR=>1514.33^oF )\)

Therefore

 \(-14-74.26=m(401-704)\)

 \(m=\frac{-14-74.26}{(401-704)}\)

 \(m=0.22\)

The barometer is a device used to measure atmospheric pressure and can be used to predict weather changes. The U-tube is a device used to measure pressure in a container and it uses a liquid to measure the pressure difference between the two containers.

Barometer: A barometer is a pressure measuring instrument that is used to measure atmospheric pressure. Barometers may also be used to predict changes in the weather. It can be divided into two main categories: mercury barometers and aneroid barometers.A mercury barometer is made up of a glass tube that has been closed at one end. This end is then immersed into a container of mercury. When the pressure in the atmosphere rises, the mercury in the tube is pushed down and when the pressure falls, the mercury rises up in the tube. The height of the column of mercury is a measure of the atmospheric pressure.U-Tube: The U-Tube is another type of pressure measuring instrument. It consists of a U-shaped glass tube that is filled with a liquid, usually water. The tube is then connected to the container whose pressure is to be measured. When the pressure in one side of the tube increases, the liquid is pushed up in that side and down in the other side. The difference in height of the two columns of liquid is then a measure of the pressure difference between the two containers.
