Answer:

Fuel efficiency for highway = 114.08 miles/gallon

Fuel efficiency for city = 98.79 miles/gallon

Explanation:

1 gallon = 3.7854 litres

1 mile = 1.6093 km

Let's first convert the efficiency to km/gallon:

48.5 km/litre = (48.5 * 3.7854) km/gallon

48.5 km/litre =  183.5919 km/gallon (highway)

42.0 km/litre = (42.0 * 3.7854) km/gallon

42.0 km/litre = 158.9868 km/gallon (city)

Next, we convert these to miles/gallon:

183.5919 km/gallon = (183.5919 / 1.6093) miles/gallon

183.5919 km/gallon = 114.08 miles/gallon (highway)

158.9868 km/gallon = (158.9868 /1.6093) miles/gallon

158.9868 km/gallon = 98.79 miles/gallon (city)

Air enters a 200 mm diameter adiabatic nozzle at 195 deg C, 500 kPa and 100 m/s. It exits at 85 kPa. If the exit diameter is 158
ahrayia [7]

Answer:

v_2 = 160.23 m/s

T_2 = 475.797 k

Explanation:

given data:

Diameter =d_1 = 200mm

t_1 =195 degree

p_1 =500 kPa

v_1 = 100m/s

p_2 = 85kPa

d_2 = 158mm

from continuity equation

A_1v_1 = A_2v_2

v_2 = \frac{\frac{\pi}{4}d_1^2 v_1^2}{\frac{\pi}{4}d_2^2}

v_2 = \frac{d_2v_1}{d_2^2}

v_2 = [\frac{d_1}{d_2}]^2 v_1

      = [\frac{0.200}{0.158}]^2 \times 100

v_2 = 160.23 m/s

by energy flow equation

h_1 + \frac{v_1^2}{2} +gz_1 +q =h_2 + \frac{v_2^2}{2} +gz_2 +w

z_1 =z_2 and q =0, w =0 for nozzle

therefore we have

h_1 -h_2 =\frac{v_1^2}{2} -\frac{v_2^2}{2}

dh = \frac{1}{2} (v_1^2 -v_2^2)

but we know dh = Cp dt

hence our equation become

Cp(T_2 -T_1) = \frac{1}{2} (v_1^2 -v_2^2)

Cp (T_2 -T_1) = 7836.94

(T_2 -T_1) = \frac{7836.94}{1.005*10^3}

(T_2 -T_1) = 7.797

T_2 = 7.797 +468 = 475.797 k

Who can work on a fixed ladder that extends more than 24 feet?
baherus [9]

Answer:

Explanation:

If the fixed ladder will reach more than twenty-four (24) feet above a lower level, you as the employer are required to incorporate a personal fall arrest or ladder safety system into the installation of the ladder. For reference, this requirement is cited in OSHA Section 1910.28(b)(9)(i).

If the total length of the climb on a fixed ladder equals or exceeds 24 feet (7.3 m), the ladder must be equipped with ladder safety devices; or self-retracting lifelines and rest platforms at intervals not to exceed 150 feet (45.7 m); or a cage or well and multiple ladder sections with each ladder section not

Why do the quadrants in coordinate plane go anti-clockwise?.
tia_tia [17]

Answer:

Quadrants are counter-clockwise because angles are measured counter-clockwise; and angles are measured counter-clockwise so that Cross Product of unit vector in X direction with that in the Y direction has to be the unit vector in the Z direction (coming towards us from the origin).
