A residential heat pump has a coefficient of performance of 1.49 How much heating effect, in kJ/h, will result when 4 kW is supp

AfilCa [17]

Answer:

21.456 kJ/h

Explanation:

See the figure attached. In this case

$W_{cycle} = 4 kW$

$Q_{out} = \text{heating effect}$

Coefficient of performance in heat pump is defined by

$COP = \frac{Q_{out}}{W_{cycle}}$

$Q_{out} =COP*W_{cycle}$

$Q_{out} =1.49*4 \, W$

$Q_{out} = 5.96 \, W$

Now it is necessary to change units, remember that Watt (W) is defined as J/s

$Q_{out} = 5.96 \frac{J}{s} \frac{3600s}{1 h} \frac{1 kJ}{1000 J}$

$Q_{out} = 21.456 \frac{kJ}{h}$

A bearing is to be used as shaft support to carry both radial and thrust forces. Calculations show that a 02 series ball bearing

shepuryov [24]

Answer:

The correct answer is "20.8 kN" and "31 kN". A further explanation is given below.

Explanation:

The angular touch bearing seems to be a fine replacement while accommodating radial and even some displacement pressures.
You may receive static as well as dynamic scores from either the manufacturer's collections.

The load ratings should be for the SKF bearing including its predetermined distance:

Static load

= 20.8 kN

Dynamic load

= 31 kN
