Answer:
force = 5.969 kN
Explanation:
given data
diameter of the hole D = 10 mm
thickness of sheet metal T = 1 mm
ultimate tensile strength = 190 MPa
solution
force is express as
force = ultimate tensile strength × Area ............1
and here area will be
area = π × D × T ................2
area = π × 10 × 1
area = 31.4159 mm²
so put value in equation 1 we get
force = 190 × 31.4159
force = 5969.02 N
force = 5.969 kN
Answer:
1141
7.2
Explanation:
The evaporator Temperature T1 = -10°C
h1 = 244.55kj/kg
S1 = 0.93782kj/kg
The enthalpy at second state from given condenser pressure from super heated refrigerant table
P2 = 600
S2 = S1
h2 = 267.19kj/kg
Enthalpy at 3 and 4 from condenser pressure
h3 = h4 = 81.5kj/kg
To get cooling load
QL = m(h1-h4)
M= 7
= 7(244.55-81.5)
= 7(163.05)
= 1141.35kw = 1141KW
COP
= h1-h4/h2 -h1
= 244.55-81.5/267.19-244.55
= 163.05/22.64
= 7.2
Answer:
3
Explanation:
it is compulsory to have a bachelor's degree
Answer:
Explanation:
Given that:
f = 250 Hz
= 2%
= 600 Hz
= 0.5 to 1.5 increment by 0.05
For 250 Hz = 250 cycle/sec
M = 0.98 , 1.02
At 0.7183 value of damping ratio the error value was 2% at 0.98 value of M
At 0.6330 value of damping ratio the error value was 2% at 1.02 value of M.
Hence, the damping ratio of the transducer must be placed between 0.6330 to 0.7183
Tempo decides the speed at which the music is played.
<u>Explanation:</u>
The Tempo of a bit of music decides the speed at which it is played, and is estimated in beats per minute (BPM). The 'beat' is dictated when mark of the piece, so 100 BPM in 4/4 compares to 100 quarter notes in a single moment.
A quick tempo, prestissimo, has somewhere in the range of 200 and 208 beats for each moment, presto has 168 to 200 beats for every moment, allegro has somewhere in the range of 120 and 168 beats for every moment, moderato has 108 to 120 beats for every moment, moderately slow and even has 76 to 108, adagio has 66 to 76, larghetto has 60 to 66, and largo, the slowest rhythm, has 40 to 60.
