Answer:
7.07%
Explanation:
Thermal efficiency can be by definition seen as the ratio of the heat utilized by a heat engine to the total heat units in the fuel consumed.
We will determine the thermal efficiency of the given problem at the attached file.
Answer:
Q=486.49 KJ/kg
Explanation:
Given that
V= 0.2 m³
At initial condition
P= 2 MPa
T=320 °C
Final condition
P= 2 MPa
T=540°C
From steam table
At P= 2 MPa and T=320 °C
h₁=3070.15 KJ/kg
At P= 2 MPa and T=540°C
h₂=3556.64 KJ/kg
So the heat transfer ,Q=h₂ - h₁
Q= 3556.64 - 3070.15 KJ/kg
Q=486.49 KJ/kg
Answer:
B
Explanation:
A robot's work envelope is its range of movement. It is the shape created when a manipulator reaches forward, backward, up and down. These distances are determined by the length of a robot's arm and the design of its axes. ... A robot can only perform within the confines of this work envelope.
Answer:
Yes, it is Reasonable.
Explanation:
The problem states that by using a new sensor, the result is 60 million dynes.
Converting the force into Newtons, by using the formula,
1 newton = 10⁵ dynes,
i.e, 1 million dynes = 10 newtons.
we get,
60 million dynes = 60 x 10 newtons = 600 newtons.
The result using a new sensor is reasonable because atmosphere exerts a force of about 10 newtons on us and 600 newtons is just 60 times of it.
Thus 600 N can be applied by the hammer on the nail and it is reasonable.
