The
work input to an ideal pump will always be greater than or equal to
the work input of an actual pump with the same working fluid, Inlet
State, and outlet pressure. True or false?
A particle
moves according to a law of motion s = f(t), t is greater than or
equal to 0, where t is measured in seconds and ? in
feet.
f(t)=t^2 •
e^(-t)
a) fine
velocity at rime t and after 1 second
b) when is
the particle at rest
c) fine the
acceleration at time t and after 1 second
8. The cardinality of S is less than or equal to the cardinality
of T, i.e. |S| ≤ |T| iff there is a one to one function from S to
T. In this problem you’ll show that the ≤ relation is transitive
i.e. |S| ≤ |T| and |T| ≤ |U| implies |S| ≤ |U|.
a. Show that the composition of two one-to-one functions is
one-to-one. This will be a very simple direct proof using the
definition of one-to-one (twice). Assume...
For each of the following, fill in the blanks with "Less than",
"Greater than", or "Equal to"
*) A gas flows through a one-inlet, one-exit control volume
operating at steady state with no internal irreversibilities, Qcv =
0. Heat transfer at a rate Qcv takes place only at a location on
the boundary where the temperature is Tb. The specific entropy of
the gas at the exit is _____ than the specific entropy of the gas
at the inlet.
