g Water at 25C, 20 bar is heated under constant pressure. a) Determine the final state if the amount of heat is 500 kJ/kgb) Determine the final state if the amount of heat is 1500 kJ/kgc) Determine the final state if the amount of heat is 3000 kJ/kg

Explanation:

Given that:

At the inlet:

Temperature

Pressure = 20bar = 2000 kPa

At the outlet:

a)

Q = 500 kJ/kg

Using the steam tables to determine the properties of water;

b)

Thus, the outlet steam will be a vapor-liquid mixture at 212.38° C

c)

Thus, the outlet steam will be a superheated vapor at 380° C

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
